Abstract

The chemically crosslinked gels based on bentonite clay of the Manyrak deposit (East Kazakhstan region) and nonionic polymer polyvinylpyrrolidone were synthesized with using the process of intercalation of the monomer in the aqueous suspension of bentonite. Swelling degree, sorption capacity of
the obtained polymer-clay composites to metal cation ions are evaluated. It is shown that with increasing the concentrations of bentonite clay in gels the sorption capacity to metal ions increases significantly.
