| Abstract: | Chelating resins (PAS) bearing dithiocarbamate groups were prepared by the reaction of carbon disulfide with resin (PA) containing secondary amine, which were obtained from polyethylene polyamines and chloromethylthiirane. The adsorption ability and selectivity of PAS for metals were determined. The order of adsorption ability of PAS for metal ions is Au3+>Pt4+>Ag+>Hg2+>Cu2+>Pb2+>Zn2+.The maxmium adsorption capacities of PAS resin for Au3+ and Ag+ are much higher than that of PA resin. PAS resin exhibits excellent selectivities for moble metals. |
