• In situ immobilization of 4-aminostyrene and methacrylic acid copolymer has beenperformed on silica gel surface. 1H NMR, IR and mass spectroscopy as well as TG analysis have been used to elucidate the structure of immobilized copolymer. An adsorption capacity of the synthesized composite towards Cu(II), Zn(II), Pb(II), Mn(II), Fe(III), Co(II), Ni(II) ions has been estimated. Adsorption activity to microquantity of Pb(II), Mn(II) and Fe(III) in a neutral aqueous medium has been observed. This chapter deals with the in situ immobilization of 4-aminostyrene with methacrylic acid copolymer on the surface of silica gel. It discusses the research of the immobilized polymer structure and its absorption properties for ions of Cu (II), Zn (II), Pb(II), Mn(II), Fe (III), and Co (II). 4-aminostyrene, as well as methacrylic acid, is polymerized in an inert atmosphere with radical initiators. Copolymerization of aminostyrenes with such active monomer as methacrylic acid, gives reason to expect the formation of sufficiently high molecular weight products. A model sample of 4-aminostyrene and methacrylic acid copolymer obtained under identical conditions in the absence of silica gel was used for the estimation of copolymer composition by 1H NMR-spectroscopy. According to 1H NMR it has been found that the ratio of 4-aminostyrene and methacrylic acid containedin the copolymer immobilized on the surface of silica is about 4:1.
