-
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 ex-traction-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.
