摘　　要：The extraction capability of auram with di-(2-ethylhexyl)monothiophosphoricacid from hydrochloric acid solution has been studied. The extraction capability decreases with theincrease of acidity. It is showed by the saturation method and equal Moore series method that thecomposition of the extraction complex is AuR_3. IR and ~1H NMR studies indicate that the extractionmechanism is a cation exchange process through coordination with P=S bonds.The extraction capability of auram with di-(2-ethylhexyl)monothiophosphoricacid from hydrochloric acid solution has been studied.
