THE KINETIC AND THERMODYNAMIC OF CHROMIUM COMPLEXES SORPTIONS’ WITH DIPHENYLCARBAZID AND CARMOAZINE USING ION-EXCHANGE RESINS CU-2-8 AND AV-17-8

Abstract

There was organized estimation of the shaping sorption layer mechanism at extraction of coordination compounds (CC) chromium (III) diphenylcarmoazonate and chromium(III) carmoazonate (CAON-Cr(III)) by ion-exchanger resins CU-2-8 and AV-17-8 surface, by using dynamic and kinetic curves, that consider functions of the filling the granules ionexchange resins’ change at time, Biot number and sorption exchanging capacity value. The calculated thermodynamic parameters at CAON-Cr(III) extraction point to chemosorption sorption’s mechanism prevalence, that is accompanied by the reorientations CC effect for ion-exchangers resins’ surfaces
