Electrochemical study and application of Pb2+ transfer across the liquid/liquid interface

Pb2+ has a sensitive complex peak in the water/acetylacetone-dithizone system. The voltammetric behavior of Pb(II) facilitated by dithizone (DzH(2)) across the water/acetylacetone interface was investigated by cyclic voltammetry. The process was controlled by diffusion and irreversible. Pb2+ transferred from water to acetylacetone to form Pb(DzH)(2) With dithizone. Pb2+ spike potential appeared at -0.3 V and the linear scope was 5 X 10(-6)similar to 0.1 mol(.)L(-1). The reliable and sensitive method can be developed for the on-line and in situ determination of Pb2+ in industrial waste water.
