SYNTHESES OF POLYSTYRENE RESINS CONTAINING POLYETHER OLIGOMERS AND THEIR EXTRACTION FOR GOLD (Ⅲ)*

Received Date: 20 July 1992

Three polystyrene resins containing polyether oligomers as extractants were synthesized andtheir extraction properties were studied. Gold (III) ion could be extracted rapidly by the resins(T1/2<1min.)with high effciency and capacity (for LS-B resin that were 99.8% and 95.8mg/gR respectively) from aqueous solution but most of the co-existing metal ions such as Pd(II),Cu(II),Zn(II),Pd(II) and Cd(II) were remained.The extraction capacity and stripping percentage for gold (Ⅲ) remained unmained unchanged in four extraction-stripping cycles.The resins also showed good column extraction-elution properties.
