Abstract

This study aims to investigate the nature and type of complexes formed in solution between 1,2-bis(2,6-dimethphenylamino) glyoxime (DPG) and the ions Ni2+, Cu2+ and Zn2+. Potentiometric titration was used to follow the formation of complexes.

The complexes formed were studied through the determination of stability constants of these complexes in mixed ethanol-aqueous solution at 25 +/- 0.1 A degrees C and ionic strength of 0.1 mola

Comparison with other vic-dioximes was made to provide reliable support for the formation of the proposed complexes in solution.
