Abstract

The back-extraction rate of bis(dithizonato)cadmium(II) was measured, and the possibility of the mutual separation of cadmium(II) from zinc(II) with dithizone by back-extraction was considered. It was found that the back-extraction rate of zinc(II) was much lower than that of Cadmium(II), which could be almost back-extracted within 40s of shaking at pH 1.8, though under these conditions zinc(II) was scarcely back-extracted at all. Based on this, the kinetic separation of cadmium(II) from zinc(II) using a back-extraction procedure could be devised.
