[Physico-chemical study of the reaction between transition metal ions and Schiff bases. Polarographic study of complexes of copper(II) with salicylidene-beta-alanine].

Copper complexes of salicylidene-alanine have been studied by polarographic method of analysis in aqueous medium and at constant ionic strength. The reduction of copper in different concentrations of schiff base at the dropping mercury electrode was found to be diffusion controlled but irreversible. The kinetic parameters (alpha and ks) were evaluated by the method of Ayabe and Matsuda. The composition and stability constants of the complex were determined by DeFord and Hume's method as modified by Vleck.
