A Mercury Free Dopamine Dithiocarbamate Modified Electrode For Pb (II) Determination by Anodic Stripping Voltammetry

Authors(4) :-J. Kavitha, S. Vasanthi, M. Devendiran, S. Sriman Narayanan

A mercury free dopamine dithiocarbomate (DDTC) modified electrode has been proposed for the anodic stripping voltammetric (ASV) determination of Pb (II). DDTC synthesized from dopamine and carbon disulfide. An ethanolic solution of this compound was drop casted on paraffin impregnated graphite electrode to prepare the modified electrode. This electrode was used for Pb (II) determination by ASV. Various parameters such as background electrolyte, pH and preconcentration time were optimized. Under optimized condition, the stripping method provided a linear range from 0.33 to 35 ┬ÁM for the determination of Pb (II) by ASV. The proposed method is simple, sensitive and selective for the determination of Pb (II) by ASV.
