Evaluation of Formation Constants of Mixed-Ligands Complexes of Cadmium(II) with Some Amino Acids (Alanine, Serine) and 4,4,4-Trifluoro-1-(2-Napthyl)Butane-1,3-Dione at DME in 60% Acetonitrile Medium

Conference paper


Intensive polarographic study of Cd(II) with amino acids (L-Serine, DL-Alanine) and the ligand 4,4,4-trifluoro-1-(2-napthyl)butane-1,3-dione have been carried out keeping constant ionic strength (μ = 1), at 308 K, by using KNO3 in 60% Acetonitrile media. It was found that the reduction of all the systems taken, are diffusion controlled and reversible involving two electrons. For the simple system of Cd(II) with 4,4,4-trifluoro-1-(2-napthyl)butane-1,3-dione and Cd(II) with amino acids, the stability constants were determined first by DeFord and Hume and then evaluated by Schaap and McMaster method.
