INORGANICIONS ON THE SORPTION-CHROMATICITY AND TEST THE DETERMINATION OF CHROMIUM(VI)

Abstract

The features of the adsorption layers mechanism in the presence of inorganic ions amounts that are typical for natural and waste waters were established by using the optical and chromaticity parameters of the systems «an aqueous solution of complex 1,5-diphenylcarbazonate of chromium(III) – the surface of the cation exchanger CU‑2‑8» and «an aqueous solution of complex chromium(III) karmoazonate – the surface anion exchanger AV-17-8». The approximation equations for finding the numerical values of color difference systems and values of Gurevich-Kubelka-Munk function are obtained.
