ABSTRACT:
The present invention relates to an adsorbent polymer having improved selectivity for cadmium ion, comprising a water-insoluble polymeric material having available surface pendant chelating groups having a multiplicity of thiol (--SH) groups, wherein pairs of thiol groups are connected by a chain R having between about 10 and 16 atoms of the structure: ##STR1## which thiol terminated chains are capable of chelating cadmium ion in rings of between about 11 and 17 atoms, and
