Abstract: A synergetic extraction-eluting resiri(Levextrel)containing petroleum sulfoxide(PSO)and N,N-di(1-methylheptyl)acetamide(N503)has been prepared. The resin has a saturated absorption capacity of 148mg Au per gram dry resin. The absorption performance of the extraction-eluting resin has been investigated. The results of coluinn separation experiments showed that the gold and palladium retained on column could be effectively eluted with 0.5% thiourea solution.

Key words: synergetic extraction-eluting resin, absorption, gold, palladium, levextrel, petroleum sulfoxide, di(1-methylheptyl)acetamide(N503)
