Динамическое концентрирование хлоридных комплексов золота (III) N-2- сульфоэтилхитозанами с различными степенями модифицирования

Abstract

In this study adsorption of the Au (III) chloride complexes on N-2-sulfoethylchitosan in fixed bed columns has been investigated and the breakthrough curves have been obtained. The dynamic sorption capacities were calculated, its meanings decreased from 0.50 to 0.095 mmol/g with increasing substitution degree of chitosan from 0.3 to 1.0. The experimental breakthrough curves have been fitted with dynamic models Thomas, Adams-Bohart, Yoon-Nelson for determination parameters of sorption process.
