Spectrophotometric Determination Of Fe, Ni, Cu, Zn, Cd, Hg With 1-(Benzimidazol-2-Yl) Ethanone Thiosemicarbazone

K.Syamasundar, M.Adharvana Chari, D.Shobha


A simple and sensitive method for the spectrophotometeric determination of Fe, Ni, Cu, Zn, Cd and Hg in trace amounts by using 1- (benzimidazol-2-yl) ethanone thiosemicarbazone (BET) as complexing agent. Metal, ligand ratios are computed as 1:2 in the metal complexes at pH 9.0. This ligand is forming stable colour with metals. The molar absorptivity, applicability of Beer’s law, stability constants and the effect of foreign ions also studied for different metal complexes.
