-
Chelating resin with macrocyclic mercaptal group supported on macroporous polystyrene beads was synthesized, which showed good selectivity to Hg2+: its complexing capacity amounted to 30—60 mg Hg2+/g resin, two orders of magnitude greater than for other metal ions such as Ca2+, Zn2+, Cd2+, Pb2+ etc. This resin could restore the activity of urease which had been deactivated by poisoning with Hg2+. Its restoring power was far better than that of the mercapto-resin and common anionic exchange resins.It showed some promising use as an oral polymeric detoxifying drug for mercury poisoning.
