Abstract

Completely water insoluble resins containing different ligand groups were synthesized by radical polymerization in solution. The yield was higher than 78%. The resins were characterized by FT-IR spectroscopy and thermal analysis. The retention properties at different pH were investigated by a batch method. Metal ions studied were: Cu(II), Cd(II), Zn(II), Hg(II), Pb(II), Cr(III), and U(VI). The retention properties were also tested under competitive conditions and were found to depend strongly on the pH. Elution of the metal ions was investigated in acid and basic media. © Wiley-VCH Verlag GmbH, 2001.
