    • Abstract


      Employing diffusion coefficient data evaluated by improved polarographic techniques, stability constants of Cd2+, Zn2+, Co2+ and Ni2+ with biochemical and chemical ligands using 0.1 M NaClO4 as supporting electrolyte were determined. The range ofβ values with biochemical ligands were higher than with chemical ligands. A similar trend of high and lowβ values was established using the Tanaka plot and Bjerrum’s method. Thermodynamic parameters reveal no chelate formation with either biochemical or chemical ligands.
