Ilyasova, X. N. "THE STUDY OF ION-EXCHANGE EQUILIBRIUM OF HEAVY METAL IONS Cо2+ AND Cd2+ ON THE NATURAL AND SYNTHETIC SORBENTS." Azerbaijan Chemical Journal, no. 4 (December 8, 2022): 122–27. http://dx.doi.org/10.32737/0005-2531-2022-4-122-127.

Abstract:
These article summaries the results of studying the sorption equilibrium of ions close to their concentration in the liquid industrial waste. For experimental research, solutions with concentration of Со2+ and Cd2+ ions in the range of 1·10-3–1·10-4 N have been used. These concentrations match to ion con¬cen¬tration in industrial liquid waste with the ions mentioned. In the experiments, the Na+- modified forms of natural sorbents based on clinoptilolite from the Aydag deposit and on bentonite from the Dash-Salakhli (Azerbaijan) deposit were used. For comparison, among industrial sorbents, we used synthetic cation exchanger KU–2–8 (styrene and divinylbenzene co–poly¬mer), which we modified in H+, Na+-form. The thermodynamic constant of ion-exchange equilibrium for differently charged ions, calculated by the Gorshkov-Tolmachev formula, does not depend on the solution concentration, and to calculate this value, it is not required to determine the activity coefficient. Based on experiments to determine equilibrium concentrations, we can recommend inexpensive and available Na-clinoptilolite and Na-bentonite instead of synthetic industrial KU-2-8 for the sorption extraction of Co2+ and Cd2+ ions from wastewater

Abstract:
Research on the potential of Ion Imprinted Polymer (IIP) selective adsorption of heavy metals using eugenol compounds and their derivatives has been carried out. Isolation and synthesis of eugenol derivatives with metal selective active groups and their use as selective metal carriers have been carried out with satisfactory results. Carrier effectiveness can still be improved by methods that focus on the target molecule recognition model. This adsorption method is called Ion Imprinted Polymer (IIP). The main components of IIP are functional monomers, crosslinkers, and target molecules. The use of acrylamide and its derivatives as functional monomers is useful with a lot of success achieved but also invites danger because it includes carcinogenic substances, a nerve poison, and so on. Moreover, the N group, which is an active acrylamide group, and its derivatives are only selective towards borderline metals (HSAB theory). Alternatives that are safe and can increase their selectivity are therefore needed. Eugenol, with its three potential functional groups, is believed to be able to replace the function of acrylamide and its derivatives that can even increase the effectiveness of IIP. The purpose of this study is to determine the potential of eugenol derivatives as selective adsorbents through the IIP method. This synthesis of IIP involved the use of basic ingredients of eugenol and its derivatives (polyeugenol, EOA, polyacetate). Each base material is contacted with a metal template then crosslinked with three kinds of crosslinking agents, namely EGDMA, DVB, and bisphenol. IIP is formed after the metal template is released using acid/HCl. The outcomes obtained demonstrate that the IIP method is able to increase the metal adsorption capacity and that the IIP method for metals is largely determined by the release of metals, which will form a hole for metal entry through adsorption. Poly-Cd-DVB, Eug-Cr-DVB, Poly-Cu-bisphenol, Polyacetate -Cr-DVB are polymer materials that have the potential to make up an IIP.

Abstract:
In this study, sulfonated polyvinyl alcohol/phosphomolybdic acid composite cation exchange membrane was prepared by solution casting method. Some of the ionb exchange peroperties such as ion exchange capacity for alkali and alkali metal ions, effect of temperature on ion exchange capacity, elution behavior, effect of eluent concentration, distribution coefficient were studied. On the basis of selectivity coefficient values some important binary separation of heavy metal ion pairs such as Hg (II)-Zn (II), Hg (II)-Cd (II), Hg (II)-Ni (II) and Hg (II)-Cu (II) were carried out. It was observed that elution of heavy metal ions depends upon the metal-eluting ligand stability. Mercury remained in column for a longer time than that of other heavy metal ions. The separations are fairly sharp and recovery of Hg (II) ions is quantitative and reproducible.

Abstract:
Keteniminium ions have been demonstrated to be remarkably useful and versatile reactive intermediates in chemical synthesis. These unique heterocumulenes are pivotal electrophilic species involved in a number of efficient and selective transformations. More recently, even more reactive ‘activated’ keteniminium ions bearing an additional electron-withdrawing group on the nitrogen atom have been extensively investigated. The chemistry of these unique reactive intermediates, including representative methods for their in situ generation, will be overviewed in this review article.1 Introduction2 The Chemistry of Keteniminium Ions3 The Chemistry of Activated Keteniminium Ions4 Keteniminium Ions: Pivotal Intermediates for the Synthesis of Natural and/or Biologically Relevant Molecules5 Conclusions and Perspectives

Abstract:
The ion flux produced by an obliquely incident Nd Q-switch pulse on a graphite target has been analyzed with regard to its kinetic energy, charge, and angular distribution. The laser intensity has been varied in a range between 109–5·1010 W/cm2, appropriate for many low-irradiance applications. It is observed that for ions of charge state n the emission cone of the number of ions scales with cos2n+1. The angular emission probability of the kinetic energy of the individual ions is found to be independent of their charge and scales as a cosine function. Due to the asymmetrical heating of the expanding plasma by the obliquely incident laser pulse, the maximum of emission is rotated away from the target normal toward the incoming laser, depending upon the ion's charge and the laser energy. The measured kinetic energy spectra are determined by the recombination during the plasma expansion: There are no low-energetic highly charged ions and no high-energetic lowly chargedions. If the laser energy (intensity) is enhanced, it is observed that the additional heating essentially serves only to increase the velocity of the higher charged ions; the energy of the individual singly charged ions is not altered.

Abstract:
The nomenclature of cations R1C(=O+R3)R2 (R1, R2, R3 = H or organyl) has been examined and shown to be in a state of immeasurable confusion: a pragmatic recommendation is made that the generic term “carbonylonium ions” should be adopted for these intermediates, which comprises the terms “aldehydium” (R1 = H, R2, R3 = H or organyl) and “ketonium ions” (R1, R2 = organyl, R3 = H or organyl) for the corresponding aldehyde- and ketone-based intermediates, respectively.
