Resumo

The results of the formation of foamed acrylamide sorption composites (SC) from suspensions of various natures under microwave heating conditions are presented. The increase in sorption properties (SP) was carried out due to the additional introduction of inorganic (manganese oxide) and organic (chitosan) sorbents into the acrylamide foam matrix. The production of acrylamide foam composites based on dispersion media with chemical reagents that react with toxic compounds and form sediments in the polymer matrix increases the sorption capacity (SC).

3. Fig. 2. To prevent the release of cobalt ions from the foam gel, the gel foaming was carried out on a solution of alkali KOH (a) or sodium hydrogen phosphate Na2HPO4 (b) as a dispersion medium. As a result of the cobalt hydroxide precipitation reaction, the release of cobalt ions from the gel matrix was reduced; 1 - initial solution of cobalt salt (0.479 M), 2 - cobalt solution after the release of cobalt nitrate from the gel into water.
