Abstract
A new polymer–mineral composite was synthesized by adsorption of the copolymer of 5-(4′-nitro)-phenylazo-8-methacryloxyquinoline with methyl methacrylate on the surface of natural saponite clay. Using computer processing of isotherms of low-temperature adsorption–desorption of nitrogen, a decrease in the specific surface area of saponite after fixing this copolymer was recorded. Using the BJH method, it was calculated that after the adsorption of the copolymer, the average pore volume of the surface of the original mineral decreases and the average pore diameter increases. The sorption capacity of the synthesized composite concerning metal ions compared to the original mineral increases.
