A Comprehensive Study on Removal of Metal Toxicity by Metal-Ligand Interaction with the Aid of SCOGS Computer Analysis

The formation of biologically significant metal chelates by metal ligand interaction of toxic metal ions Hg (II) and Pb (II) with suitable amino acid and nucleobase used as ligand have been studied at silver-silver chloride electrode by the potentiometric technique in 1: 1: 1 and 1: 2: 1 molar ratio for ternary and 1: 1: 1: 1 molar ratio for quaternary complexes. The stability constants of investigated complexes were determined by analyzing with SCOGS computer programme at temperature 37 1oC and the ionic strength I = 0.1 M (NaNO3).
