Some aspects on the stability of metal(II), methionine and metal(II), methionine, pencillamine (binary & mixed) complexes an paper electrophoretic technique

摘要

Stability constants of binary [Pb(II) - methionine], [UO2II) - 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 35 degrees C.
