Abstract:

This article studied the effects of chemical fixation with magnesium oxide, calcium oxide, aluminum oxide, ferrous sulfate+calcium oxide in situ on Arsenic and Cadmium combined contamination soils. The results indicate: Four agents have well fixation effects, and the fixation effect of ferrous sulfate and calcium oxide mix- restoration is the best. However, it increases the leaching toxicity of Cadmium; Aluminum oxide also has a certain fixation effect on Arsenic, but it strengthens the leaching toxicity of Cadmium in acidity condition; the fixation in situ effects of magnesium oxide and calcium oxide on Arsenic and Cadmium combined contamination soils, which dramatically decreases the leaching toxicity of Arsenic and Cadmium and makes two pollution elements co-stabilized.

Abstract:

Cadmium oxide (CdO) thin films were deposited using the sequencing ion layer adsorption and reaction (SILAR) method. In this study, the effect of the pH value of an aqueous solution of cadmium acetate at a concentration of 0.2 mol of the cadmium oxide film was determined. The solution source for the cadmium oxide film was cadmium ions and an aqueous ammonia solution. The CdO films were deposited on glass substrates at a temperature of 90 ℃. The cadmium oxide film thickness was determined by the weight difference method at pH values (7.2, 8.2). X-ray diffraction (XRD) and scanning electron microscopy (SEM) showed that the size of the crystals increased with the increase in the solution (pH). While the UV-visible spectra of the films revealed that the optical band gap energy decreases with increasing (pH) of the CdO solution. The absorbance spectrum of the cadmium oxide film was recorded in the wavelength range (300 – 900) nm. The change in the pH of the cadmium acetate aqueous solution from the energy gap and X-ray diffraction calculations showed that the film had an optical band gap energy and that the highest intensity was at (111) and that the membrane is n-type, as shown by studies to prepare the cadmium oxide membrane using the SILAR method.

Abstract:

Synthesis of nanocrystalline cadmium oxide particles were explored by the reaction of inorganic precursor (cadmium chloride) and alkali (sodium hydroxide) via modified wet-chemical method followed by annealing at various temperatures (250, 500 and 750 °C). The structural, optical and morphological studies of cadmium oxide samples were carried out by X-ray diffraction, infrared, ultraviolet-visible, and scanning electron microscope techniques. From X-ray diffraction analysis, it was confirmed that cadmium oxide particles furnish a face centred cubic phase structure and revealing a grain size of around 59 nm. The scanning electron microscope micrographs admit that cadmium oxide samples are agglomerated and have spherical shapes. The bonding deformation and stretching frequency results of cadmium oxide samples were obtained from infrared spectra. The corresponding increase in calcination temperatures has shown an increase in particle size while as no change was found in band gape. These results attribute that the variation in annealing temperature has a significant role on the crystalline nature, grain size and its optical properties. Furthermore, the synthesized cadmium oxide samples were examined for bioactivity analysis.

Abstract:

The present study proposes a simple synthesis technique for producing bunsenite cadmium oxide nanoparticles. A variety of techniques were used to determine the structure, morphology, elemental content, and optical properties of bunsenite cadmium oxide nanoparticles. The samples’ XRD spectra at 500 °C and above confirmed the presence of cubic bunsenite and cadmium oxide structures. The crystallite size was increased from 29 nm to 62 nm as the calcined temperature increased from 500 °C to 800 °C. The dispersion of the particles of bunsenite cadmium oxide improved with an increasing calcination temperature. An equivalent increasing trend was indicated by the mean grain size displayed via field emission scanning electron microscopy (FESEM) micrographs. Furthermore, the UV-Vis spectra showed that multiple energy band gaps attenuated as the calcination temperature increased. The mean particle size, as measured by transmission electron micrographs, appeared to increase in tandem with the calcination temperature. The obtained bunsenite and cadmium oxide nanoparticles have potential for employment in a wide range of semiconductor applications.

Cadmium oxide thin films were prepared by D.C magnetron plasma sputtering using different voltages (700, 800, 900, 1000, 1100 and 1200) Volt. The Cadmium oxide structural properties using XRD analysis for just a voltage of 1200 volt at room temperature after annealing in different temperatures (523 and 623) K were studied .The results show that the films prepared at room temperature have some peaks belong to cadmium element along the directions (002), (100), (102) and (103) while the other peaks along the directions of (111), (200) and (222) belong to cadmium oxide. Annealed samples display only cadmium oxide peaks. Also, the spectroscopic properties of plasma diagnostic for CdO thin films were determined and the results show that the electron temperature and electron density increase with increasing of sputtered voltage.

Abstract:

The toxicity of inhaled aerosols of cadmium chloride (CdCl2) and cadmium oxide (CdO) on hepatic biochemical function was compared. Male rats were exposed for 2 hours to concentrations of 0.45 and 4.5 mg Cd/m3. Serum and liver enzymes and histological changes were studied immediately and 72 hours after exposure. Exposure to 4.5 mg/m3 CdCl2 and CdO resulted in an increase in liver Cd content. This deposition was not observed at the lower concentrations. Following exposure to 4.5 mg/m3 CdCl2, decreases in body and liver weight, as well as decreased activities of glutathione (GSH)-reductase, GSH-peroxidase, and glucose-6-phosphate dehydrogenase (G-6-PDH) were observed. Increases in serum bilirubin and activities of creatine kinase, lactate dehydrogenase, and aspartate aminotransferase were evident 72 hours after exposure. Exposure to 4.5 mg/m3 CdO caused decreased activities of GSH-reductase and peroxidase, G-6-PDH, and an increased activity of serum alkaline phosphatase and lactate dehydrogenase. Exposure to 0.45 mg/m3 CdCl2, produced more hepatic effects than did a similar exposure to CdO. This differential response between inhalation of CdCl2 and CdO was probably due to a rapid clearance of CdCl2 or Cd2+ ions from the lung and transport to the liver via the systemic blood circulation.

Abstract:

Cadmium oxide was synthesized using oleic acid as the precursor and capping agent, the main role of oleic acid to cap the formed cadmium oxide and to control the particle size. The formed cadmium oxide nanoparticles were characterized by using FT-IR, XRD,FE-SEM and cyclic voltammetry. The electrochemical detection of pollutants (4-Nitrophenol and 2-Nitrophenol) was carried out by coating the cadmium oxide onto the glassy carbon electrode (GCE) by drop coating method. The electrocatalytic performance of the modified GCE electrode was best with 4-Nitrophenol. In case of 2-Nitrophenol the electrocatalytic performance was not observed but increase in current response indicates the ability of modified electrode to be a useful one for sensing the environmental pollutants.

Abstract:

Cadmium sulfide (CdS) semiconductor thin films were grown on sapphire single-crystal substrates. Indium oxide (In2O3) and zinc oxide (ZnO), which are typical transparent conducting materials, were heteroepitaxially grown on sapphire substrates as underlayers before the cadmium-based semiconductor thin films were grown on them. Subsequently, cadmium-based thin films were heteroepitaxially grown on the transparent conducting under-layers. Crystallinity and photoluminescence properties of the cadmium-based thin films grown on the underlayers were evaluated and compared with those of the cadmium-based thin films grown directly on sapphire substrates.

Abstract:

In the current research, Cadmium Oxide (CdO) nanoparticles are produced by ultrasonic waves and the effect of nucleic acids (DNA/RNA) doping on their optical and structural characteristics are investigated. X-ray Diffraction (XRD) analysis confirms extension of peaks and formation of Cadmium Oxide (CdO) nanoparticles. Absorption spectra for the produced samples are shown that addition of DNA/RNA affects the spectrum and absorption edge shifts towards blue region which is due to reduction of nanoparticle size and it confirms by SEM images. In addition, SEM images show the formation of approximately single size ellipsoidal nanostructures for pure Cadmium Oxide (CdO). However, the size, form and distribution of nanoparticles are varied after doping. On the other hand, in the current paper, Cadmium Oxide (CdO) and DNA/RNA/Cadmium Oxide (CdO) nanostructures thin layers are produced using spray pyrolysis technique over a glassy substrate. Annealing of CdO thin layer for half an hour in the air leads to improvement of crystalline structure. Optical characteristics and crystalline structure of samples are studied through X-ray Diffraction (XRD) and UV-Visible spectroscopy. The results of the current study were shown that CdO thin layers are of hexagonal structure. Further, optical gaff of CdO/DNA/RNA/glass thin layer is increased compared to CdO/glass layer.

The real dielectric constant, dielectric loss factor, and tangent were calculated in the frequency range (50 to 1000000 HZ). It was found that the partial substitution of cadmium oxide plays an important role in enhancing dielectrically properties.

Abstract:

Nickel-doped cadmium zinc borate glass of various nickel oxide content was prepared as xNiO–20ZnO–60B2 O3 –(20-x) CdO (0≤x≤5 mol %), by the melt quenching method based on nano metal oxides. Both the zinc oxide nanoparticles (ZnO NPs) and cadmium oxide nanoparticles (CdO NPs) were prepared via the solution–combustion technique. Nickel oxide nanoparticles (NiO NPs) was synthesized by the combustion of Ni(OH)2 and boron oxide nanoparticles (B2 O3 NPs)was synthesized by the solid-state reaction method. The amorphous nature of these types of glass was confirmed using X-ray diffraction analysis (XRD). The morphology of nano-metal oxides was investigated via the scanning electron microscope (SEM). SEM imaging showed that the NiO NPs had a semi-spherical morphology, and that their average particle size was 22.17 nm. The Fourier-transform infrared spectroscopy’s (FTIR) spectral analysis was used to identify the structural units of these types of glass via deconvolution, in terms of multi-Gaussian fitting. Results proved that Ni 4+ plays an important role and a key to improve the formation of the BO4 network units. Finally, the high thermal stability and glass transition temperature of the prepared glass samples were increased by increasing the loading of NiO NPs from 0.0 mol % - 5.0 7k = mol % and this was established by using DTA.

Abstract:

Graphene materials have attracted increasing interest in water remediation. In this study, magnetic graphene oxide (MGO) was prepared through the modified Hummers method and the adsorption behaviors of cadmium were investigated. Firstly, the sorption kinetics, isotherms, as well as the effects of pH were investigated. Then, fractional factorial design (FFD) was used to optimize the effects of pH, temperature, time, initial concentration of cadmium ion and NaCl on cadmium adsorption. The results indicate that MGO could effectively remove cadmium ions from an aqueous solution and the sorption data could be described well by pseudo-second-order and Freundlich models, showing that the adsorption rate of cadmium ions on MGO is multilayer adsorption and dominated by the chemical adsorption. According to the FFD results, the maximum adsorption capacity of cadmium ions was 13.169 mg/g under the optimum condition of pH value 8, 45 °C, contact time 60 min, initial cadmium concentration of 70 mg/L and NaCl concentration of 100 mg/L. Higher levels of the pH value, temperature and initial cadmium concentration are beneficial to the adsorption process. These results are important for estimating and optimizing the removal of metal ions by MGO composite.

Abstract:

In this work, the effect of temperature of the ablation environment on the properties of Cadmium Oxide (CdO) nanoparticles produced by synchrotronic laser ablation method is investigated. To produce nanoparticles, Nd:YAG synchrotronic laser pulse with 1121 (nm) wavelength is used to emit Cadmium in the cancer cells. All test parameters were kept constant and cancer cells temperature was changed to produce samples at 20 and 65 °C. Then, ATR-FTIR, XRD, TEM and UV-Visible spectroscopy analyses were performed to investigate their properties. The results show that the size of nanoparticles is increased by increase in temperature of ablation environment. On the other hand, in the current experimental research, DNA/RNA-Cadmium Oxide (CdO) complex is created at the size of Nano. In this regard, same volume of DNA/RNA and Cadmium Oxide (CdO) solutions were mixed together and emitted by the second harmonic synchrotronic laser pulse of Nd:YAG with wavelength of 777 (nm). The DNA/RNA and Cadmium Oxide (CdO) solutions have been produced, separately, using synchrotronic laser ablation process. To produce them, synchrotronic laser pulse of Nd:YAG with wavelength of 1121 (nm) and pulse width of 7 (ns) and repeating frequency of 5 (Hz) was used. The results show that synchrotronic laser emission with wavelength of 777 (nm) is an appropriate method for producing DNA/RNA compounds in the size of Nano.

In this work, the effect of temperature of the ablation environment on the properties of Cadmium Oxide (CdO) nanoparticles produced by synchrotron radiation is investigated. To produce nanoparticles, synchrotron radiation pulse with 1064 (nm) wavelength is used to emit Cadmium in the human cancer cells, tissues and tumors. All test parameters were kept constant and human cancer cells, tissues and tumors temperature was changed to produce samples at 20°C and 65°C. Then, ATR–FTIR, XRD, TEM and UV–Visible spectroscopy analyses were performed to investigate their properties. The results show that the size of nanoparticles is increased by increase in temperature of ablation environment. In addition, in the current experimental research, Gold (Au)–Cadmium Oxide (CdO) alloy is created at the size of nano. In this regard, same volume of Gold and Cadmium Oxide (CdO) solutions were mixed together and emitted by the synchrotron radiation pulse with wavelength of 532 (nm). The Gold and Cadmium Oxide (CdO) solutions have been produced, separately, using synchrotron radiation ablation process. To produce them, synchrotron radiation pulse with wavelength of 1064 (nm) and pulse width of 7 (ns) and repeating frequency of 5 (Hz) was used.

Abstract:

Cadmium is one of a heavy metal which widely used in human life, especially in the electroplating industry and a mixture of textile materials. Cadmium that enters the body binds to the metallothioneins protein. It can increase the formation of free radical compounds, there by inhibiting enzyme activity such as nitric oxide synthase3. This gene regulates the expression of endothelial nitric oxide synthase which produce a nitric oxide. Nitric oxide role in regulated blood pressure as vasodilator with Angiotensin II as vasoconstriction. The susceptibility to Cd exposure will elevate if the polymorphisms of gene is found in population. The aim of this research was to know effect of cadmium to gene NOS3 polymorphisms on NO, systolic and diastolic blood pressure and antioxidant enzyme in Cd-exposed individual. The genotype individual were detected by Polymerase Chain Reaction-Restriction Fragment Length Polymorphisms (PCR-RLFP) with MBo1 restriction enzyme. Parameter recorded were blood Cd , NO level, SOD, systolic and diastolic. Data were analyzed by independent t-test. These result showed that 20% of 40 individual of cases subject were detected as polymorphisms individual of NOS3gene, with GA genotype. Their fragment DNA located on 206 bp, 119 bp and 87 bp, but non polymorphisms of NO gene is only located on 206 bp. The result show cadmium could influence polymorphisms NOS3gene and decrease NO production followed by increasing of blood pressure both systolic and diastolic. Cadmium also decrease antioxidant enzyme SOD and GPx level.

Abstract:

The cadmium-doped SnO 2 nanoparticles have been successfully prepared by a simple mechanochemical reaction and subsequent thermal treatment. The samples were characterized using X-ray diffraction (XRD), scanning electron microscope (SEM) and energy dispersive spectroscopy (EDS). Thermal treatment of the as-milled powder at 700°C for 2 h resulted in the formation of Cd-SnO 2 nanoparticles with an average crystal size of 13 nm, varying with the calcination temperature. The effect of doped cadmium on the crystal size of the nanoparticles was investigated. The lattice parameter (c) of the Cd-SnO 2 nanoparticles, lower than that of pure SnO 2, decreased with increasing amount of doped cadmium. The apparent activation energy of Cd-SnO 2 nanocrystal growth during calcination of the precursor was calculated to be 70.8 kJ/mol. The mechanochemical method is a novel, cheap and convenient technique especially suitable for large-scale synthesis of nanosized materials.

Abstract:

Metals in oil and gas fluids have been of concern to the environmental and industrial communities since 1976. As a result, metals in 31 spent drilling fluids representative of the major oil and gas production provinces in the Continental United States, were fractionated into exchangeable, bound to carbonates, bound to Fe-Mn oxides, bound to organic matter, and residual forms using a sequential extraction (summation of fractions) technique. Bioavailability and mobility of metals in solid matrices follow in sequence of the operational defined fractions with chemical reactivity decreasing in the order of exchangeable > bound to carbonate > bound to Fe-Mn oxide > bound to organic matter > residual fractions. Metals evaluated in this study include arsenic, barium, cadmium, chromium, lead, and zinc. The summation of fractions was compared to independent total metals analysis using the United States Environmental Protection Agency (USEPA) SW-846 Method 3050 digest procedure to evaluate metal recoveries. No difference was observed in the summation of fractions and EPA Method 3050 total metal values for arsenic, barium, and cadmium. EPA Method 3050 digest was about 28 percent lower in chromium, and about 19 percent lower in lead and 16 percent lower in zinc than the total by summation of fractions. Almost all of the barium (95.6 percent) was recovered in the residual fraction. Arsenic was recovered primarily in the residual fraction (74.3 percent) and the Fe-Mn oxide fraction (16.1 percent). The highest quantity of cadmium was recovered in the residual fraction (43.3 percent), followed by the bound to organic (27.9 percent), and bound to Fe-Mn oxide (21.1 percent) fractions. Chromium was observed primarily in the residual (40.4 percent) and bound to Fe-Mn oxide (34 percent) fractions. Lead was distributed primarily in the bound to Fe-Mn oxide (49.3 percent), and residual (27 percent) fractions. Zinc was almost equally distributed in the bound to organic (36.2 percent), and bound to Fe-Mn oxide (33.1 percent) fractions. Cadmium (3.9 percent) and arsenic (2.7 percent) were the only metals with an exchangeable fraction >1 percent of the total. Low total and/or low exchangeable metal concentrations ultimately control the bioavailability and mobility of metals in spent drilling solids and limit the potential for an adverse impact on the environment.

Abstract:

In this work, polymer composites of high density polyethylene reinforced by micro-sized and nanosized cadmium oxide, lead oxide, and a mixture of both with filler weight fraction of 30% were prepared by compression molding technique and characterized by scanning electron microscope. This investigation aims to present a comparative study between cadmium oxide and lead oxide according to their sizes as fillers in high density polyethylene polymeric matrix for gamma-radiation shielding applications. The mass and linear attenuation coefficients of the investigated composites were measured as a function of g-ray energies ranging from 59.53 keV to 1408.01 keV using standard radioactive point sources (241Am, 133Ba, 137Cs, 60Co, and 152Eu). The measurements were made with a narrow beam geometry setup using a well calibrated hyper pure germanium cylindrical detector. The theoretical values of the mass attenuation coefficients were evaluated using the XCOM program database. The experimental results demonstrated that, according to the filler size, cadmium oxide composite is better as a gamma absorber in the energy region less than 81 keV, while lead oxide composite is better in the energy region greater than 81 keV. Moreover, for the same chemical structure and weight fraction of the composite, nano fillers show better attenuation performance than micro fillers in high density polyethylene based radiation shielding material.

Abstract:

Background: Heavy metals, even at low concentrations, are harmful to human health and environment. Cadmium as a heavy metal is highly toxic and can cause serious threat to living organisms. This research was designed to evaluate the adsorption potential of modified magnetic iron nanoparticles by 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol ligand for the removal of cadmium ions from water solutions. Methods: This study was conducted in Ilam Branch, Islamic Azad University, Iran, in 2014. Modified magnetic iron nanoparticle was used as adsorbent for the removal of cadmium from aqueous solution. In batch extraction, the effects of parameters like pH of sample solution (3.0-11.0), initial metal concentrations (50-300) mgL-1), contact time (1.0-10 min) and adsorbent dose (10.0-60.0 mg) were studied on the adsorption process. Modified magnetite nanoparticle was presented as the adsorbent for the removal of cadmium ions from aqueous samples and later was confirmed by flame atomic absorption spectrometry. Results: The adsorption of cadmium ions on modified magnetite nanoparticles strongly depends on pH. The experimental isothermal data were analyzed using the Langmuir and Freundlich equations. The removal process followed the Langmuir isotherm. Maximum adsorption capacity for the adsorption of cadmium ions by the sorbent was 24.09 mgg-1. Conclusion: The method was successfully applied to adsorption of cadmium in water samples with satisfactory results. Other advantages include high capacity, good stability and fast adsorption kinetics. High pre-concentration factor was obtained easily by this method (120) and low analysis cost.

Abstract:

We have studied the structural and thermophysical properties of cadmium oxide (CdO), using the Three-Body Potential (TBP) model. Phase transition pressures are associated with a sudden collapse in volume. The phase transition pressures and related volume collapses obtained from this model show a generally good agreement with available experimental others data. The thermophysical properties like molecular force constant, Debye temperature, and so forth, of CdO are also reported.

Abstract:

This paper has experimentally proved that hydrogen accumulates in large quantities in metal-ceramic and pocket electrodes of alkaline batteries during their operation. Hydrogen accumulates in the electrodes in an atomic form. After the release of hydrogen from the electrodes, a powerful exothermic reaction of atomic hydrogen recombination with a large energy release occurs. This exothermic reaction is the cause of thermal runaway in alkaline batteries. For the KSL-15 battery, the gravimetric capacity of sintered nickel matrix of the oxide-nickel electrode, as hydrogen storage, is 20.2 wt%, and cadmium electrode is 11.5 wt%. The stored energy density in the metal-ceramic matrix of the oxide-nickel electrode of the battery KSL-15 is 44 kJ/g, and in the cadmium electrode it is 25 kJ/g. The similar values for the KPL-14 battery are as follows. The gravimetric capacity of the active substance of the pocket oxide-nickel electrode, as a hydrogen storage, is 22 wt%, and the cadmium electrode is 16.9 wt%. The density of the stored energy in the active substance oxide-nickel electrode is 48 kJ/g, and in the active substance of the cadmium electrode it is 36.8 kJ/g. The obtained results of the accumulation of hydrogen energy in the electrodes by the electrochemical method are three times higher than any previously obtained results using the traditional thermochemical method.
