説明

The separation of cations has been studied by circular chromatography with a new type dithizone-impregnated silicagel thin layer, and the results were compared with those by the paper chromatography.<BR>The thin layer has been prepared by adding 30 ml of 0.3% dithizone-chloroform solution to 10 g of silicagel (Wakogel B-O). The cations are separated to form colored chromatograms of concentric circles of metal chelates. For the sample solution of a mixture of Hg²⁺, Cu²⁺, Cd²⁺, Ni²⁺ and Zn²⁺, the best results were obtained by the developer with either 12N acetic acid: acetone=1 : 1 or 24N acetic acid: acetone =1 : 0.66. The colored chromatograms obtained were much clearer than those by dithizone-impregnated paper chromatography.
