Synthesis and Adsorption Properties of 4-Aminostyrene And Methacrylic Acid Copolymer, Immobilized in Situ on Silica Surface

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.
