Spectrophotometric Determination Of Fe, Co, Ni, Cu, Zn, Cd, Hg With 1-Methyl, 2-Acetyl Benzimidazole Thiosemicarbazone

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

A simple, sensitive and selective method for the spectrophotometric determination of Fe, Co, Ni, Cu, Zn, Cd and Hg in trace amounts by using 1-methyl-2-acetyl benzimidazole thiosemicarbazone as complexing agent. The coloured complex is stable and metal ligand ratios are observed as 1:2. The molar absorptivity, Beer’s law applicability, stability constants and effect of diverse ions are studied.
