Chromatographic separation of inorganic ions on thin layers of titanium phosphate ion-exchanger

doi:10.3724/SP.J.1123.2014.06031

Abstract

Abstract:

The chromatographic behavior of 30 inorganic cations has been studied on thin layers of titanium phosphate ion-exchanger using several aqueous, organic and mixed mobile phases. The separation of one ion from several other ions and also ternary and binary separations have been developed. Some important analytical separations are reported. The effect of pH of the mobile phase on retention factor (R_f) values of the cations in the presence of complex-forming anion along with the separation power of the ion-exchanger were studied. This ion-exchanger exhibits high sorption capacity and varying selectivity towards metal ions and makes it a suitable stationary phase in thin layer chromatography.

Key words: separation, thin layer chromatography (TLC), titanium phosphate
