Abstract
Reversed-phase paper chromatographic separations of As(III), Sb(III) and Bi(III) have been camed out on Whatman No 1 filter paper lmpregnated with tnphenylphosphine oxide as stationary phase and using organic complexmg agents such as sodium acetate, sodium succinate and sodium malonate solutions as active mobile phases. Results for the separation of binary and ternary mixtures are reported and the method has been successfully applied to the separation and detection of these elements present in real samples and at ppm level concentration.
