Study of Binary and Ternary Metal Complex formation by Peptides by Solution Electrophoresis in Solution [Cu (II)/Ni (II)/Co (II)/Zn (II) - Glycyl Sarcosine -NTA-System]

摘要

An innovative solution electrophoresis technique has been used for the study of mixed complexes of some divalent metals ions viz. Cu (II), Ni (II), Co(II) and Zn(II). with Glycyl Sarcosine as primary ligand and NTA as secondary ligand.. The stability constants of the mixed complexes formed were found to be: 6.64,4.85,4.53,4.42 (Log k values) for Cu (II), Ni (II), Co(II) and Zn(II) respectively at 30°C an ionic strength 0.1 M.
