Abstract

Electrophoretic technique has been used for the study of Fe^III, Cu^II, Ni^II, Co^II-methionine binary and Fe ^III, Cu^II, Ni^II, Co^II-methionine-NTA (nitrilotriacetic acid) ternary complexes. The stability constants of metal-methionine binary complexes are found to be 10^6.03, 10 ^5.23, 10^5.13, 10^4.23 and the stability constants of metal-methionine-NTA ternary complexes have been found to be 10^6.35, 10^6.04, 10^5.87, 10^5.80 for Fe^III, Cu^II, Ni^II and Co^II complexes respectively at μ = 0.1 M (HClO₄) and 25°C.
