Sorption properties of silica gel with adsorbed copolymers of 4-vinylpyridine and styrene with respect to Cu(II), Pb(II) and Fe(III) ions

A number of new organo-mineral composites in different mass ratios of organic and inorganic components were obtained by adsorption on the silica gel surface of 4-vinylpyridine–styrene copolymer. Th...
