Kinetics of copper and cobalt ion exchange on inorganic antimony-containing ion exchangers

Abstract

The exchange capacity, degree of exchange, and separation factors of copper(II) and cobalt(II) ions on the H-form of the inorganic ion exchanger “polysurmin”, a silicon phosphorus antimony ion exchanger, and a composite material based on polysurmin were studied as functions of the ion exchanger contact time in the solution. The results were treated in order to assess the rate-limiting step of the process.
