Abstract:
The excess of Lead in the human blood is extremely dangerous for their health specially for their nervous system. We have been studied mixed ligand complexes of imidazole (Im), glycine(gly1-) and alanine (ala1-) with Pb (II) with make Pb soluble and exrete it thrugh urine. The stability constants of these soluble complees [Pb(gly) (Im)]1+, and [Pb(ala (Im)]1+ are log β11=7.26, log β11=7.56, respectively at pH 7.3 and 25±0.1°C. The value of stability constant is determined by polarographic method.
