Abstract

The electrochemical detection of free chlorine based on the reduction at a gold electrode has been studied. The differential pulse voltammetric curves exhibited well-defined cathodic peaks. Investigations with this system suggested that the active species in the cathodic reaction is HClO. Excellent reproducibility was demonstrated at pH-5. The peak height could be used for accurate and rapid determination of free chlorine in a sample water. A linear relationship (r2=0.99) was found for the concentration range of 1-5-mg-Cl-dm-3 and the detection limit was estimated to be 0.04-mg-Cl-dm-3.
