Abstract

In the present communication ionophoretic technique has been used for the study of Fe^III, Cu^II, Ni^II, Co ^II-cystine binary and Fe^III, Cu^II, Ni ^II, Co^II-cystine-NTA (nitrilotriacetic acid) mixed complexes. The stability constants of metal-cystine binary complexes are found to be 10^7.80, 10^6.90, 10^5.10, 10^4.66 and the stability constants of metal-cystine-NTA mixed complexes have been found to be 10^5.18, 10^4.88, 10^4.76, 10 ^4.10 for Fe^III, Cu^II, Ni^II and Co^II complexes respectively at μ = 0.1 M (HClO₄) and 25°C.
