Kinetics of ion metals exchange on the ionexchanger “Polysurmin” and on composite materials based on it

Abstract

The kinetics of ion exchange of copper, cobalt, calcium, potassium and cesium on an inorganic ion exchanger “polisurmin” from antimony and silicon and the composite material from “polisurmin” and an organic polymer has been investigated. It was found that the degree of exchange of close to 1, achieved during 2 days or less, with at polisurmine exchange is faster. It was shown that the kinetic dependences of the investigated ions are generally similar, but have individual features. Value reaches capacity and its time dependence depend on the composition and structure of the resin and the properties of the absorbing ion. Results have been evaluated, so far as is possible under the given conditions, in order to define the limiting stage of the process. Selectivity rows have been formed. Refs 18. Figs 6. Tables 4.
