Abstract

A systematic study of the structural effects of dialkyl(aryl) sulfides on the extraction equilibra of Au (III) and Pd (II) are reported. Dialkylsulfides are excellent extractants with high capacities and selectivity for Au and Pd from HC1 solution. The extraction behavior of dialkyl(aryl)sulfides may be controlled by polar and steric substituents effect. The distribution data suggested that the extracted species were AuCl₃ R₂S and PdCl₂SUB 2R₂S, respectively.
