Abstract
Abstract The adsorption behaviour of 48 metal ions has been studied in Oxalic acid - Oxalate systems using silica gel - G layers. The effect of pH on Rf values was also investigated. A plot of -log Ksp Vs. RM and Rf shows the dramatic behaviour of Hg2+ ion in 0.1 M Potassium Oxalate + 0.1 M Ammonium Oxalate (1:1) system. A number of interesting separations have been achieved e.g., Fe3+ - Ti4+ zr4+ - Ti4+, ce4+ - La3+, zr4+ - Th4+, Te4+ - Se4+ and Zr4+ - Y3+ - La3+. Ti4+ and Nb5+ were separated from a mixture of number of ions.
