Abstract: The synergistic effect of the extraction of Au( Ⅲ) from HCl medium with N1923 (primary amine)-Ph3POin CHC13 was investigated. The effects of the concentration of AuCl4- Cl- and H+ ions in aqueous phase and that of Ph3POand N1923 in the organic phase on the synergistic extraction of Au( Ⅲ ) with N1923-Ph3PO-CHCl3 were studied respectively by the slope method.
