ABSTRACT:

The reduction of Pb(II) in the aqueous solution with some amino acid (glycine and valine) and thiodiglycolic acid (TDGA) have been investigated at dropping mercury electrode first by the method of Deford and Humes and that of Pb-amino acids-TDGA have been studied by the method of Shaap and McMasters. The reduction of all the complexes has been found to be reversible and diffusion controlled, involving two electrons in each case. Three types of mixed complexes MXY, MX2Y and MX2Y have been determinedand found to be more stable than that of the simple ones. With the help of these data statistical and electrostatic have been considered.
