Abstract
Separation and determination of eight inorganic ions by thin-layer chromatography were examined. The metallic ions of Hg2+, Cu2+ and Pd2+ were extracted with dithizone chloroform solution at pH 0-1 (1 N HCl solution) and those of Ni2+, Co2+, Zn2+, Bi3+ and Pb2+ at pH 7-8. These dithizonates were separated on MN-silica gel layer by using carbon tetrachloride-methylene-chloride-benzene (1 : 7 : 4) as a developer. The chromatogram of each dithizonate was determined by densitometry. The coefficient of variation of these determined dithizonates was 0.89-9.81%. This method seemed to be applicable to a simplified determination.
