Abstract:
In this study, the resins modified with trimellitie anhydride (named ZT3) or phthalic anhydride (named ZT5) during the post-crossing of chloromethyl low crosslinking macroporous poly-styrene resin were prepared, characterized and evaluated for adsorptive removal of o-aminobenzoic acid (OABA) from aqueous solutions. The structural characterization results indicated that the resins possessed predominant micropores surface area and moderate specific surface area. The adsorption performance of OABA onto ZT3 and ZT5 was studied through static and kinetic adsorption experiment with the commercial Amberlite XAD-4 as a contrast. Langmuir and Freundlich isotherm equation could fit the adsorption isotherm of OABA onto ZT3 and ZT5 perfectly. The adsorptions of OABA onto the three resins were all spontaneous exothermic processes with physical characters. Kinetic analysis showed that the adsorption reaction could be approximated by a quasi-first kinetic adsorption equation. Key words: o-aminobenzoic acid; adsorption resin; adsorption kinetic; thermodynamic; che-mical modification

An equation is suggested which allows the prediction of the values of adsorptional Henry constants for a given adsorbent and various adsorptives at any temperature, in terms of the known experimental adsorption isotherm for an adsorptive on the same adsorbent at a given temperature. The potential application of the suggested method has been tested using known experimental data and the conditions for its use in the analysis of adsorption equilibria in different systems are discussed.

Abstract:
Atomic adsorptions of N, C and O on silicene and molecular adsorptions of N2 and CO on silicene have been investigated using the density functional theory (DFT) calculations. For the atomic adsorptions, we find that the N atom has the most stable adsorption with a higher adsorption energy of 8.207 eV. For the molecular adsorptions, we find that the N2 molecule undergoes physisorption while the CO molecule undergoes chemisorption, the corresponding adsorption energies for N2 and CO are 0.085 and 0.255 eV, respectively. Therefore, silicene exhibits more reactivity towards the CO adsorption than the N2 adsorption. The differences of charge density and the integrated charge calculations suggest that the charge transfer for CO adsorption ([Formula: see text]0.015[Formula: see text]) is larger than that for N2 adsorption ([Formula: see text]0.005[Formula: see text]). This again supports that CO molecule is more active than N2 molecule when they are adsorbed onto silicene.

Abstract:
A magnetic multi-walled carbon nanotube/zeolite nanocomposite was applied for the adsorption and removal of arsenic ions in simulated and real acid mine drainage samples. The adsorption mechanism was investigated using two-parameter (Langmuir, Freundlich, Temkin) and three-parameter (Redlich–Peterson, and Sips) isotherm models. This was done in order to determine the characteristic parameters of the adsorptive removal process. The results showed that the removal process was described by both mono- and multilayer adsorptions. Adsorption studies demonstrated that a multi-walled carbon nanotube/zeolite nanocomposite could efficiently remove arsenic in simulated samples within 35 min. Based on the Langmuir isotherm, the adsorption capacity for arsenic was found to be 28 mg g−1. The nanocomposite was easily separated from the sample solution using an external magnet and the regeneration was achieved by washing the adsorbent with 0.05 mol L−1 hydrochloric acid solution. Moreover, the nanoadsorbent was reusable for at least 10 cycles of adsorption-desorption with no significant decrease in the adsorption capacity. The nanoadsorbent was also used for the arsenic removal from acid mine drainage. Overall, the adsorbent displayed excellent reusability and stability; thus, they are promising nanoadsorbents for the removal of arsenic from acid mine drainage.

Abstract:
Based on the experiment in lab and the investigation in study site, we have studied the adsorption of fine sand, medium sand and coarse sand which composes the aquifer. The different type's soil is different to the petroleum adsorption, the adsorptive capacity of fine sand is strongest, the coarse sand adsorption is worst. The adsorptive capacity of Sandy in 33.8% to 46.1%, adsorptive capacity of gravel is 9.2%. Freundlich model is more accurate to explain the sorption of the sands. The adsorption reaction of sand is very rapid, and it often only needs less than a day to reach adsorption reaction balance. The pollution levels are underestimated, and has been underestimated approximately 37.1% to 41.4%, and adsorption attenuation is a main action in study site.

Abstract:
A systematic, hybrid density functional theory study of interaction between SiGe nanotubes (SiGeNTs) and X (X = H, O, H2 and O2) have been performed using the hybrid functional B3LYP and an all electron 3-21G* basis set implemented in GAUSSIAN 09 suite of software. All possible internal and external adsorption sites were considered, and it was found that H prefers to move onto top of an atom site while O prefers to incorporate into NT wall by breaking the bonds. Adsorption energies for H is ∼2.0 eV and for O it is ∼5.0 eV. Controlled adsorption of atomic H and several molecular O give rises to defect density states in the frontier orbital region. H rich adsorptions predict the difference between highest occupied molecular orbital (HOMO) energy and the lowest unoccupied molecular orbital (LUMO) energy increase while O rich adsorptions predict the decrease in HOMO-LUMO energy gap. O and O2 adsorptions predict definite ionic bonding character while H atomic adsorptions predict covalent bonding. H2 is very neutral towards the adsorption into SiGeNTs and clearly shows the physisorption adsorption. Considering the all adsorptions, the adsorptions happened within the Si vicinity of the SiGeNT shows the most stable and preferred adsorption region.

"Exploring the Potential of TNT and Aniline Coexistence to Enhance Their Transports in Saturated Chinese Loess."

Full text
Abstract:
To determine the interactions between TNT and aniline adsorptions and the potential to enhance their transports in saturated Chinese loess, batch and column tests were conducted. The batch tests show that their adsorptions inhibit each other when they coexist, and their inhibitions depend on their concentrations, implying that their coexistence has the potential to enhance their transports of each other in the saturated loess. The column tests confirm this speculation, while aniline enhances TNT transport more obviously than TNT does. These findings are ascribed to TNT adsorption being primarily through surface adsorption, while aniline adsorption mainly takes place via electrostatic adsorption and inner pore diffusion adsorption, as well as surface adsorption. There is a certain competitive relationship in their adsorptions on the loess because they have same and different adsorption sites; in particular, electrostatic force is greater than surface force. Therefore, these inhibitions on adsorption are conducive to the existences of TNT and aniline in the water rather than being fixed on the loess, thus enhancing their transports in the saturated loess, indicating that their coexistence can increase the risk of soil and even groundwater pollution.

Abstract:
Abstract A new adsorbent material MIL-101(Fe, Al)/MoS2 was composed by a solvothermal pathway for the adsorption of tetracycline hydrochloride simulated wastewater. The material was analyzed through XRD. Influences of adsorption time, initialization concentration, and pH on adsorptive effect were explored. It turned out that MIL-101(Fe, Al)/MoS2 on tetracycline hydrochloride adsorption reached equilibrium at approximately 180 min and the adsorptive amount of MIL-101(Fe, Al)/MoS2 for tetracycline hydrochloride was 118.96 mg/g at adsorption equilibrium. In contrast to MIL-101(Fe, Al), the adsorptive effect of MIL-101(Fe, Al)/MoS2 composite material on TC was substantially improved. The adsorptive process was more in accord with the Lagergren second-order kinetic model and Langmuir adsorption isotherm model. Besides, the TC adsorption on MIL-101(Fe, Al)/MoS2 was better under neutral conditions.

The present research set a goal of study of applicability of the expanded perlite obtained on the basis of perlite – natural mineral of Georgia, from adsorption removal of Fe3+ ions from aqueous solution. Adsorptive characteristics of the expanded perlite have been studied in the process of aqueous solution purification from trivalent iron ions in regard to adsorbent dosage, contact time, adsorbate concentration and solution pH. The dependence of adsorption degree and adsorptive capacity of the expanded perlite from the above-mentioned parameters have been uncovered. Optimum conditions of Fe3+ ions adsorption have been established. Maximum values of adsorption degree and adsorptive capacity were equal to 89% and 4,45mg/g, respectively.

Abstract:
In this thesis, relationships between the hydrodynamics and adsorption behaviour within EBA columns were examined and methods to improve EBA performance in terms of productivity, reproducibility and control were provided. The effect of column verticality was quantified and identified as a significant source of process variability. Column misalignment of only 0.15° off vertical resulted in a greater increase in liquid dispersion in 1 cm diameter columns compared to 5 cm diameter columns. Protein breakthrough curves for vertical and 0.15° off-vertical runs performed using a 5 cm diameter column were essentially indistinguishable, while applicability more protein could be applied to a vertical 1 cm diameter column compared to the same column misaligned by 0.15°. This degree of misalignment was not detectable by visual assessment of adsorbent particle movement within the column, therefore methods were developed to ensure column verticality for separations at the smaller scale. Equipment and methods for in-bed sampling of both liquid and solids were developed. A 5 cm diameter EBA column was modified to allow abstraction of samples from ports positioned along the columns wall. The modifications to the column did not significantly affect liquid dispersion or separation efficiency. It was demonstrated that on-line, in-bed sampling can provide higher control of a separation. The in-bed monitoring system was also used to study hydrodynamics within a vertical 5 cm diameter column with a perforated plate distributor, the same column aligned 0.15° off-vertical, and a 5 cm diameter column which employs a stirrer for flow distribution.

Abstract:
The interactions of CO, NO and O2 with Pt{111}, pt{211}, and Pt{411} have been investigated with Single Crystal Adsorption Calorimetry (SCAC). Coverage-dependent heat of adsorption and sticking probability data for 300 K are presented, and are discussed with respect to the kinetics and thermodynamics of adsorption and desorption. CO adsorption proceeds molecularly on both Pt{111} and Pt{411}, with initial sticking probabilities of 0.78 and 0.80, and initial heats of adsorption of 176 kJ mol-1 and 196 kJ mol-1, respectively. Both adsorbate layers are found to be non-localised, having identical pre-exponential factors of 2x1015 s-1. Discrepancies between isosteric and calorimetric heat of adsorption data at low coverage for CO/Pt{111} have been rationalised in terms of an entropy-driven localised/non-localised phase transition occurring above 300 K. Initial adsorption of NO occurs with a sticking probability of 0.84 on all three surfaces. The initial heat of adsorption for NO/Pt{411} indicates dissociative adsorption. The NO/Pt adsorbate layers are found to be highly localised, with pre-exponential factors in the range 1017 – 1020 s-1. This has been discussed in terms of desorption from highly compressed adsorbate layers in which co-operative effects are extant. O2 adsorption proceeds dissociatively on all three surfaces, with the initial heats of adsorption all above 300 kJ mol-1. Desorption occurs from localised adsorbate layers, with all systems having pre-exponential factors of 1018 s-1. A kinetic compensation effect has been observed for the data of this thesis, as well as that of the SCAC literature, and is discussed within the context of the chemisorption entropy-enthalpy compensation.

Abstract:
Chromatography is a widely used separation technique including many different modes, for example supercritical fluid chromatography (SFC) which uses a supercritical fluid as mobile phase. A supercritical fluid is achieved when a substance is subjected to a temperature and pressure above the critical point and the boundary between the liquid phase and gas phase is erased. The interest for SFC has increased in recent years, mainly for separation of chiral molecules in the pharmaceutical industry. What makes SFC interesting is that it is a quick, cost-efficient and green method. This is in part due to less organic solvent used in the mobile phase in SFC compared with liquid chromatography and that the carbon dioxide that represents the major part of the mobile phase is a by-product from other processes. In SFC modifiers, often small alcohols, are added to carbon dioxide based mobile phase in order to increase the solubility of polar compounds. In this study the adsorption of methanol to two different stationary phases; Kromasil-Diol and chiral Lux Cellulose-4 were studied. Adsorption is a phenomenon where surface interactions crate a higher density of molecules at the surface than in the bulk. The aim of this work has been to study the adsorption of modifier (methanol) to the stationary phase both to determine the extent of adsorption and the kinetics for system equilibration. These findings were then put into perspective of normal use of SFC for separation of molecules. There are a number of techniques for measuring adsorption; in this study the tracer pulse method is used. This is a pulse method where a concentration plateau is created and an isotope labelled molecule is injected. This was performed in the mobile phase composition from pure carbon dioxide to pure methanol. In addition to the tracer pulse experiments the isotope effect, the eluent flow, equilibration times for the column and retention times for a set of analytes were measured. For the Diol column no large isotope effect was observed, the method was also proved to be highly reproducible since several runs gave consistent results. Calculations based on the experimental data showed that a 6.3 Å thick layer was built up at a methanol fraction of 13% (v/v), corresponding to a monolayer. Changes of the methanol fraction below the saturation level has has greater effect on the retention factor for the analytes than at higher methanol fractions, when the monolayer was saturated. The conclusion of this is that SFC is more stable in the area where the layer has been built up. A preliminary study has been made for the chiral Lux Cellulose-4 column which was not as conclusive as for the Kromasil-Diol column. This type of column needs further studies to confirm the deviating observations and to investigate the cause for these.

Thermal energy storage has received significant interest for delivering heating and cooling in both transportation and building sectors. It can minimize the use of on-board electric batteries for heating, ventilation and air-conditioning (HVAC) in electric vehicles (EVs) or reduce electricity consumption during peak demand in residential and commercial buildings. A compact and lightweight advanced thermo-adsorptive battery (ATB) is currently being developed to provide both heating and cooling. Additionally, if waste heat or solar energy were used to regenerate the ATB, the mechanical energy to run the cycle for vapor compression and transport, can be eliminated, thus, providing a significant benefit over conventional HVAC systems, especially when provision of electric energy is challenging. We present a detailed characterization of the thermophysical and transport properties of adsorptive materials for the development of the ATB. We discuss the feasibility of using contemporary adsorptive materials, such as zeolite 13X, by carrying out a detailed experimental and theoretical characterization. Enthalpy of desorption of zeolite 13X - water pair was characterized using the state of the art calorimetric technique. The experimental characterization and theoretical modeling of commercially available zeolite 13X (Sigma Aldrich, molecular sieves, 13X, powder, ~2 [mu]m average size) combined with carbon nano-materials, such as functionalized multi-walled carbon nanotube and graphene, are carried out to improve the effective thermal conductivity. Furthermore, we carried out performance characterization of a single-layer adsorption stack for the development of the ATB. Consequently, this thesis can serve as a framework for the development and characterization of adsorption-based thermal storage systems.

Abstract:
Due to the fact that the worldwide energy consumption caused by cooling devices in buildings has been increasing steadily and also the fact that the pressure has been rising to provide this cooling energy with environmentally friendly technology, solar powe.re~ DEC-systems (Desiccative and Evaporative Cooling) have begun capturing increasing interest over the past few years. , However, up to now little experience has been gained in the operation of these systems and thus currently little information is available about the performance, the efficiency, the control strategy and the best component choice. This lack of knowledge has resulted in a low rate of acceptance of, this technology so far. The studies presented in this thesis serve as a contribution to the advancement of DEC technology by providing fundamental knowledge about the operation and attainable performance of these systems. A comprehensive study of desiccant wheels was undertaken which provides detailed information about the operation and the achievable dehumidification performance of this component. A detailed simulation model for desiccant wheels was developed and verified with measured data from a desiccant wheel test plant. Additionally, two commercially used DEC-systems (one in a public library in Spain and the other in a plastics processing factory building in Germany) were monitored for the purposes of evaluating the performance of these systems and resolving existing problems in their operation and control strategies. In spite of the generally positive validation of the planned and expected cooling performances in both cases, the monitoring also showed that there are considerable possibilities· for improvement, especially with the regulation of the system.

Full text
Abstract:
The work presented in this thesis draws upon several uses of STM, from structural determination, when used in conjunction with theoretical simulations, to the observation of surface reactions and surface mediated interactions. Simulations have been used here for the first time to allow the complete structural determination of a complex reconstruction. The determination of the reconstruction's structure and composition has enabled further experiments involving the oxidation of the Ag{111} surface as well as adsorbate-oxygen interactions mediated by the surface. The source of inspiration for these studies has been the catalytic epoxidation of ethene on silver by atomic oxygen. Two 'surface' states of atomic oxygen have been observed. The first, denoted Oc, is considered to adsorb in interstitial sites within the top layer of AG{111}. Its adsorbate-adsorbate repulsive nature sees this species rapidly saturating at a coverage of just 0.05 ML, at which point the p(4x4)-O species becomes more stable and its growth is nucleated at step edges. On decomposition of the p(4x4)-O reconstruction, both Ag{111} triangular islands and fractures within the oxide appear across the terraces. Both features may play a significant role in the catalytic behaviour. Ethene adsorption on clean Ag{111} has provided information on the adsorption geometry, adsorption state and appearance in the STM image allowing confident interpretations of the coadsorbed ethene-oxygen system. Tip pulsing has been used to provide a controlled mechanism for the induced transition from the physisorbed intrinsic precursor state of ethene to that of the chemisorbed state. High-resolution images have enabled the direct observation of Friedel surface oscillations surrounding the chemisorbed state. To my knowledge, this is the first direct observation of such oscillations resulting from adsorbates.

Abstract:
Abstract Gas adsorption-desorption highly affect gas storage and production behaviour in shale nanopores. The study of methane adsorption isotherm in shale has been extensively conducted experimentally. The shale compositions and reservoir conditions prominently control the adsorption capacity of methane. However, to date, there is a lack of discussion on the effect of heterogeneous TOC towards the adsorption isotherm and comparison with adsorption isotherm modelling. This study used the gravimetric method for supercritical methane adsorptions - desorption isotherms measurements. Isotherms measurements were conducted with three shale samples with various TOC values (9.67, 13.9, and 15.4 wt.%) from the Eagle Ford formation at pressure up to 10 MPa and temperature at 120 °C. The isotherms gathered were fitted with standard adsorption-desorption isotherm models, Langmuir, Freundlich and extended Sips to test the applicability of these models depicted the adsorption of supercritical methane. The results show that EF C with the highest TOC content (15.4 wt.%) has the highest adsorption-desorption methane capacity, more than 0.7 mmol/g, compared to other samples. The composition differences between these samples indicate that the organic contents were likely a major controlling factor of the adsorption capacities obtained. The TOC provides a higher surface area for adsorption to occur. Thus, a higher adsorption-desorption capacity was observed through this study. On the other hand, the adsorption and desorption curves did not intercept due to the hysteresis caused by the capillary condensation. The significant binding capacity of the shale surface for methane gas molecules leads to the hysteresis observed during methane desorption. It was observed that the Freundlich model was the most accurate adsorption model in describing the adsorption-desorption behaviour with tested shales with average R2 more than 0.90 and ARE (%) less than 10 % compared to other models with 15.8 % (Langmuir) and 18.9 % (Sips). This study also proved the influence of organic matter on predicting the adsorption-desorption capacity with adsorption isotherms highlighting the importance of modelling the TOC of shale with adsorption isotherm to determine the adsorption-desorption properties.

Abstract:
This article presents a thermodynamic framework for the estimation of the minimum driving heat source temperature of an advanced adsorption cooling device from the rigor of Boltzmann distribution function and the condensation approximation of adsorptive molecules on adsorbent porous surface. The calculated resuls are validated with our own experimentally measured data. From this thermodynamic analysis, an interesting and useful finding has been established that it is possible to develop an adsorption cooling device that operates with a driving heat source temperature as low as 40 °C along with a coolant of temperature 30 °C. We have also presented here the thermodynamic modeling and experimental investigation of an advanced adsorption chiller for understanding its working principles.

Abstract:
The present work is the first case where the adsorptive removal of the most commonly used antibiotic - azithromycin from aqueous solution as a model of wastewater treatment plant effluent by acid-modified natural zeolite - clinoptilolite has been investigated. The adsorption processes were carried out under static and dynamic conditions. The acid-modified form of the above-mentioned natural zeolite were obtained with hydrothermal treatment by using 2M hydrochloric acid solution. In order to investigate the adsorption dynamic process, there was used the specially constructed laboratory dynamic type instrument with a fixed bed adsorption glass column and a high-pressure pump. The effect of the inlet concentration, the flow rate and the pH value of the antibiotic influent solution, also, the contact time of system zeolite/antibiotic solution in the adsorption process were studied. The adsorption was evaluated using the Langmuir adsorption model. In order to determine quantitively azithromycin in influent and effluent solutions, a new effective and specific high performance liquid chromatography method was used. The results have been shown that the studied acid-modified clinoptilolite were characterized with high dynamic adsorption capacity. The adsorption mechanism was mainly composed of electrostatic interaction between the zeolite surface and adsorbate - azithromycin. This study has been shown and proved that acid-modified natural clinoptilolite could be an efficient, eco-friendly, alternative and competitive adsorbent in terms of cheapness, selectivity and adsorption efficacy for the removal of azithromycin from hospital, pharmaceutical industrial wastewaters and wastewater treatment plant effluents.

Abstract:
Rich in aromatic carbon and minerals, biochar is produced by biomass pyrolysis at temperatures ranging from 350 °C to 1000 °Cin low-oxygen environment. Traditionally biochar was applied to soilto improve its fertility and carbon sequestration. However, due to low production costs, availability of the feedstock and specific biochar properties related to adsorption of contaminants from aqueous solutions, biochar has gained much interest in other fields, e.g. health sciences and engineering. The aim of the study was to distinguish the types of biochar modifications and to determine biochar characteristics contributing to adsorption. This paper is focused on recentexperimental studies related tobiochar modifications enhancing the adsorption of contaminants. Mechanisms of adsorption and the key factors affecting adsorptive properties of biochar are analyzed. Finally, recommendations for further research in designing the biochar are proposed.

Abstract:
The first phase of the study was designed to determine the adsorption rate of viruses and microspheres to sandy and loamy soils and determine the adsorption efficiency of various viruses to soil. The adsorption of viruses to sandy and loamy soils has been found virus type dependent. The poorest adsorption was observed for MS2 bacteriophage while the greatest adsorption was observed for PRD-1. Adsorption sites on the soil material were not found as limiting factors for adsorption of viruses on soil material. The effect of water quality on adsorption has been found as virus type dependent. The adsorption process of microspheres to soil material has been found to be similar to that of viruses and occurs within a very short period of time. Carboxylated (negatively charged) microspheres seems to adsorb more efficiently than plain microspheres to soil material. At low temperatures (10oC), and under saturated conditions no virus die-off was observed, therefore under these conditions virus can survive for long period of time. At 23oC, and saturated conditions, the greatest die-off was observed for MS2 bacteriophage, whereas, negligible die-off was for PRD-1 bacteriophage and hepatitis A virus. Considering the survival results MS2 bacteriophages is not suitable as indicator for pathogenic viruses persistence in soil material. Furthermore, temperature, is more important than any other factor for the inactivation of viruses.

Abstract:
This report investigates the integration of steam adsorption chillers as a modernization strategy for conventional central steam plant systems. Our objective is to assess the feasibility, advantages, and challenges of incorporating steam adsorption chillers into existing steam plant setups to enhance energy efficiency and cooling capabilities. Central steam plant systems have historically been used for steam-based heating but often lack cooling capabilities, necessitating additional cooling infrastructure. Steam adsorption chillers offer a potential solution by using waste steam for cooling, optimizing energy utilization and reducing reliance on traditional cooling methods. Through a comprehensive analysis, this report evaluates the technical compatibility and potential cost implications of implementing steam adsorption chillers. It explores factors such as system integration, operational dynamics, and maintenance requirements to provide a holistic view of the feasibility and benefits of this modernization approach. The findings aim to offer valuable insights to decision-makers and Army facility managers seeking innovative ways to upgrade central steam plant systems. By considering the technical and economic aspects of adopting steam adsorption chillers, this report contributes to the knowledge base for sustainable and efficient energy utilization in central plant operations.
