摘要：

The extraction of palladium(II) from hydrochloric acid solutions by high molecular weight amines (trioctylamine,TOA; trioctylmethylammoniumchloride, TOMAC) in benzene has beer. investigated under different conditions. As a result, it is found that the extraction efficiency for palladium(II) with TOA and TOMAC is in the order TOMAC > TOA. The distribution coefficients for TOA and TOMAC decrease with increasing aqueous acidities. In addition, the equilibrium equations for the extraction of palladium(II) from hydrochloric acid solutions by TOA and TOMAC are proposed on the basis of the. results obtained.
