An innovative solution electrophoresis technique has been used for this study of methyl cysteine complexes of some metals ions viz. Th (IV), Fe (III), Cr (III) and Al (III). 1 : 1 complex is formed by Th (IV) while 1:1 and 1:2 complex is form by Fe (III), Cr (III) and Al (III). The stability constant of the complexes formed were found to be : log k1 = 8.25 (for Th (IV)), log k1 = 7.84, log k2 = 6.83 (for Fe (III)), log k1 = 7.64, log k2 = 4.72 (for Cr (III)), log k1 = 7.33, log k2 = 5.15 (for Al (III)) at 35°C and ionic strength 0.1 M.
