Abstract : Different stationary phases were used to obtained effective separation of Cr 6+ ,Fe 3+ , Cu2+ ,U6+ , V5+ , Ni 2+ , Co2+ and Ag+ from their three and four component mixtures by thin layer chromatography. The separations were carried out on Silica gel G, Urea Formaldehyde polymer, Cellulose, Mixture of Urea Formaldehyde & Cellulose, Mixture of Urea Formaldehyde & Silica using aqueous solutions of cationic and anionic surfactants as mobile phase. Of all above adsorbent, silica gel-G and urea formaldehyde were found to be most suitable adsorbents. The effect of concentration and pH of the mobile phase on the Rf values of individual metal ions were studied and optimum conditions for separation of metal ions from their mixture were established. Up to mixtures of four components could be effectively separated by anionic surfactant( Sodium Dodecyl Sulphate) as mobile phase while only ternary mixtures could be separated by cationic surfactant (Benz Alkoniun Chloride) as a mobile phase. Keywords: SDS,Urea Formaldehyde , TLC, Separation.
