THE KINETIC AND THERMODYNAMIC OF CHROMIUM COMPLEXES SORPTIONS’ WITH DIPHENYLCARBAZID AND CARMOAZINE USING ION-EXCHANGE RESINS CU-2-8 AND AV-17-8
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 ion- exchange resins’ change at time, Biot number and sorption exchanging capacity value. The calculatedthermodynamicparametersat CAON-Cr(III) extractionpointtochemosorption sorption’s mechanism prevalence, that is accompanied by the reorientations CC effect for ion-exchangers resins’ surfaces.
