The Simultaneous Determination of Cu Pb Cd and Sb by Derivative Adsorption Chronopotentiometry

Department of Chemistry Shandong University, Jinan 250100

Received Date: 25 February 2000

The behaviour of the complexes of copper, lead, cadmium and antimony with salicylfluorone (SAF) adsorbed on HMDE has been investigated by derivative chrono potentiometry in NH₃/NH₄Cl.The dependence of the peak height on the dt/dE vs E curve on preconcentration time, the pH of solution and the constant reducing current are discussed.This method achieved the simultaneous determination of copper, lead, cadmium and antimony in human hair.
