摘　　要：Six novel resins impregnated with polyether or polythioether oligomers have been synthesized and their extraction properties have also been investigated.Gold(Ⅲ） and /or palladium (Ⅱ） coulld be extracted repidly by the resins with high percentage and capacities from aqueous solution but most of the co-existing base metal ions were remained.The extraction capacities and stripping percentage were approximately unchanged after four extraction-elution cycles and the resins also showed excellent column extraction-elution properties.Six novel resins impregnated with polyether or polythioether oligomers have been synthesized and their extraction properties have also been investigated.
