摘要：

Amino functionalized polyacrylamide can be used as a polymeric chelating agent. In this work silica has been used as an inorganic support for organic polymer. Silica has been silylated with vinyltrichlorosilane, and then it is polymerized with acrylamide in the presence of benzoyl peroxide as an initiator. Polyacrylamide supported on silica has been transamidated with ethylenediamine to give poly(N-2-aminoethylacrylamide) immobilized on silica. This modified silica has been characterized with FT-IR, DSC, and elemental analysis and it is complexed with Cu(II), Co(II), Fe(III), Ni(II). Metal uptake capacity of this modified silica towards metal ions, especially Cu(II) cation, is several times greater than other silica-bound complexing agents such as silica modified 8-hydroxyquinoline and organic amines.
