Thermodynamics of the Sorption of Cerium Complex Compounds on Anionite

Russian Journal of Physical Chemistry A, 2013
Sorption of cerium in the form of complexes with Trilon B (EDTA) from acid media at pH 3 using weakly basic anionite D-403 in nitrate, chloride, or sulfate forms is studied. The equation of the mass action law is linearized for ion exchange reactions, allowing us to calculate the limiting sorption of ethylenediaminetetraacetate cerate (EDTA cerate ...

Sulfur Dioxide Adsorption in a Magnetically Stabilized Synthetic-Anionite Bed

Theoretical Foundations of Chemical Engineering, 2000
Removal of low-percentage SO2 from gases by adsorption in magnetically stabilized beds of a synthetic anionite-synthetic magnetite mixture in an axial magnetic field was studied. The mixture-stabilization conditions were established, and the volumetric mass-transfer coefficients were estimated as a function of the operating conditions.

Investigating Complex Formation of Palladium in Desorption Eluates From VP-1P Anionite

Russian Journal of Non-Ferrous Metals, 2012
Complex forms of palladium that are formed in ammonia-nitrate solutions during the desorption of platinum group metals (PGMs) from the VP-1P anionite are investigated.

Use of Gabriel reaction to obtain anionites

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1975
A study was made of the reaction of the chloromethylated styrene-divinylbenzene copolymers, with gel and macroporous structures, with phthalimide and its derivatives, and also the subsequent polymerlike transformations of the obtained polyimides. The optimum conditions for obtaining weakly basic anionites by the Gabriel reaction were determined.

Application of inorganic anionites as catalysts for oxyalkylation of alcohols

Reaction Kinetics & Catalysis Letters, 1991
The low thermal stability of anion exchange resins, which prevents them from being used as catalysts for oxyalkylation of alcohols, can be solved by the application of the inorganic anionite — mercarbide, a promising catalyst.

Use of Anionites for Water Softening and Demineralization

Materials Science Forum, 2018
In the paper we determined the dependence of the parameters of purified on anionite water on its salt composition, hardness and shape of the anion exchanger used. It is shown that the capacity of the ion exchanger in the CO32- form is higher in chlorides and sulfates than in the OH- -form.

Effect of heat treatment on the degradation of fiber anionites

Polymer Science Series B, 2012
The thermal transformations of anionites synthesized on the basis of a polyacrylonitrile fiber are studied. During the heat treatment of the weakly basic anionite FIBAN A-5, the cleavage of amino groups occurs via two routes. In the case of the strongly basic anionite FIBAN A-6, dealkylation and deamination occur during heating and the dealkylation of ...

Synthesis of Inter-Reticular Anionites for Uranium Sorption

Atomic Energy, 2017
A new method for modifying ion-exchange resins was developed in order to improve the performance of industrial ionites used in the extraction of uranium. It consists in using polymer matrices made from several interpenetrating low-linkage polymer networks, which are obtained by repeated polymerization of a mixture of mono- and divinyl monomers ...

Complexation of Cu(II) with Hetarylformazanes in Solutions, Polycrystals, and Modified Anionite

Russian Journal of Coordination Chemistry, 2005
The Cu(II) complexes with hetarylformazanes (HF) formed in solutions, polycrystals, and AN-18 polymeric ionite modified with HF were studied by EPR method and were found to have almost identical structures. The configuration of the Cu2+ coordination surrounding (square-planar or pseudotetrahedral) is specified by the substituents at N1 in formazane ...

Sorption of gallium from the alkali solutions based on anionites

Russian Journal of Non-Ferrous Metals, 2013
The sorption of gallium from alkali solutions on various weakly and strongly basic anionites is studied in dynamic conditions, and the breakthrough dynamic exchange capacity and complete exchange dynamic capacity are investigated. The D-403 selective anionite is selected.
