MIXED CHELATES OF CADMIUM(II) WITH N-(2-HYDROXYETHYL)ETHYLENEDIAMINE AND SOME AMINO-ACIDS

An extended method of W. B. Schaap and D. L. McMasters has been applied for the study of mixed-ligand complexes of Cadmium(II) with N-(2-hydroxyethyl) ethylenediamine (heda) and some amino acids polarographically at DME. The reduction of mixed-ligand complex at DME has been found to be reversible, and diffusion controlled at temp (30 plus or minus 0. 5) degree C and mu equals 1. 0 M (KNO//3). The formation of MXY, MXY//2, and MX//2Y has been used to discuss the non-existence of MX//3 complexes, where X has been used for heda and Y for amino acids.
