Popis: In situ modification with copolymer of 4-vinylpyridine and styrene (molar ratio 3:1) of natural mineral saponite from deposit Tashkivske(Ukraine) by radical polymerization was carried out. Anchorage of organic polymer 4-vinylpyridine-co- styrene on the mineral surface was proved by IR spectroscopy, mass spectrometry and scanning electron microscopy. The amount of immobilized copolymer in the synthesized composite material according to the thermogravimetric analysis is 8.5 wt.%. The recorded adsorption capacity of the composite with respect to Cu(II), Pb(II) and Fe(III) ions was increased in comparison with native mineral saponite.
