EQUILIBRIUM CONDITIONS, ADSORPTION KINETICS OF THE GeO2-Cu(II)-NaCl SYSTEM ON DIAION CRBO2 ANIONITE AND DESORPTION MODE FROM SPENT COLUMNS

Abstract

The IR spectrum of DIAION CRBO2 anionite synthesized on the basis of a chelating agent, a styrene macromolecule with a glucamine functional group, has been studied. Sorption properties of anionite with respect to the germanium(IV)-copper(II)-Cl-system have been studied.. It is shown that the interaction of hydroxyl and amino groups of anionite with germanate and copper(II) ions is based on the formation of corresponding complexes. Various variants of sorption isotherms are constructed, calculation equations are proposed, which are followed by isotherms, the role of external, mixed and internal diffusion on the basis of the kinetic mechanism of processes is clarified.The desorption mode of the studied components from the treated anionite column was determined.
