Correlation Between Chromatographic Behaviour and Stability Constant of Metal Ions on Diethylenetriamine Thin Layer

Abstract

The stability constants of the complexes formed between diethylenetriamine and the metal ions -V, Th, As, Pb, Zr and Se have been determined by pH metric method and these values, together with the stability constants for the metal ions -Co, Zn, Cd, Hg, Cu, Ni and Ag already reported, have been utilised to show their correlation with chromatographic behaviour of these metal ions on silica gel G plates impregnated with diethylenetriamine.
