摘要：

The extraction of Au(III) with the extractant trioctylmethylammonium chloride (TOMACl) dissolved in toluene and the same extractant impregnated in a polymeric resin XAD-2 has been studied, The results of gold extraction with both systems were compared. They showed similar gold extraction behaviour (extracted species), although greater amounts of extractant were needed when impregnated resins were used, Liquid-liquid and solid-liquid procedures can be used to extract gold selectively from solutions containing zinc and copper.
