摘要：

The extraction of zinc(II) and cadmium(II) salicylates from an aqueous solution has been studied into cyclohexane containing tributyl phosphate in the pH range 5.0 to 6.5. The effect of various variables such as pH of the aqueous phase, salicylic acid and tributyl phosphate concentrations on the extraction has been examined. From these data the extracted species are found to be of the type M(H Sal)2·2L(M = Zn2+ or Cd2+ and L = TBP. Apparently the synergistic effect takes place owing to the displacement of coordinated water by neutral donor molecules. It has been observed that the formation and distribution constants for cadmium(II) are higher than those for zinc(II). © 1979.
