Abstract
Thin layer chromatographic method has been developed for the separation of metal ions such as Cr⁶⁺, Cr³⁺, As³⁺ ,Cd^2+, Tl³⁺ and Hg²⁺ from their two, three and four component mixtures. The separations were performed on thin layer of silica gel ‘G’ using aqueous L - Valine as mobile phase. The effect of concentration and pH of mobile phase on the R_f values of individual metal ions were studied and the optimum conditions for separation of metal ions from their mixture were determined.
