“…A literature survey shows little information about preparation of hydrogels by radiation polymerization, especially those containing sulfur groups. However, a few studies, including recovery for metal ions by hydrogels containing sulfur groups, were reported 1–6. So, the present work is aimed at the γ‐radiation polymerization synthesis of a specific hydrogel containing a sulfur compound.…”

A new hydrogel that contains sulfur is prepared by radiation polymerization and its application for recovery of Hg2+, Pb2+, Cd2+, and Cu2+ ions is discussed. The metal hydrogel complexes are isolated and characterized by using different spectroscopic techniques (UV‐visible, IR, NMR, and mass), thermal analysis (TGA and DSC) measurements, and SEM. Also, the mode of complexation is determined using IR and NMR spectroscopy. The scanning electron micrographs show that the hydrogel has a great ability to recover the metal ions in the following order: Hg2+ > Cd2+ > Pb2+ > Cu2+. TGA thermograms are used to investigate the mechanism of thermal decomposition. © 2000 John Wiley & Sons, Inc. J Appl Polym Sci 77: 955–966, 2000
