  • Stability constants of binary [Pb(II) ­ methionine], [UO2(II) ­ methionine] and mixed [Pb(II) ­ methionine ­ penicillamine], [UO2(II) ­ methionine ­ penicillamine] complexes have been determined by Paper Electrophoretic Technique at ionic strength 0.1 M. The stability constants of [Pb(II) ­ methionine ­ penicillamine] and [UO2(II) ­ methionine ­ penicillamine] mixed complexes were found to be 6.60 ± 0.09 and 9.05 ± 0.13 (logarithm of stability constant values), respectively at a temperature of 35C
