A new amperometric method for titrating residual chlorine, using dual polarizable electrodes, is discussed. It has been shown to be as accurate and precise as the existing amperometric method in determinations on both water and sewage effluents. The stirring motor may be driven by d‐c current, resulting in a portable apparatus for field applications. The D.P.E. method does not require sensitizing electrodes for titrations of sewage effluents and eliminates the maintenance required for a reference electrode. In addition, the method does not require continuously balancing the cell current during the course of a titration, thus permitting more rapid titrations.
