Abstract A voltammetric membrane electrode system has been modified and applied to the in situ measurement of chlorine dioxide. The electrode system consisted of a gold cathode, a silver/silver chloride reference electrode, and a gold counter electrode. Different membrane materials were tested; silicone rubber polymeric membranes were found to be most suitable. Electrode applications involved the use of both steady state and pulse voltammetric techniques. Pulse voltammetry was primarily used for trace analysis since the sensitivity observed was about 4200 times greater than under steady state conditions. This electrode system will find its widest application in water supply disinfection processes using chlorine dioxide. It offers the unique advantage of being sensitive to gaseous chlorine dioxide and not to oxychlorine ions. Chlorine dioxide is a much more powerful disinfectant than oxychlorine ions. Furthermore, the electrode system can be used for in situ monitoring of ClO2 levels and the automatic control of the generation and dosing of chlorine dioxide.
