Peroxodisulfate measurement using boron-doped-diamond electrodes
Peroxodisulfates are strong oxidizing species with various ap-plications. Among others two particularly interesting applica-tions of these compounds are, on one hand, their use as the efficient oxidizing reagent for chemical synthesis, and on the other hand their capacity to act as a non-halogenated agent for water disinfection, e.g. in swimming pools . For these ap-plications, as well as for the control of the peroxodisulfate pro-duction processes, it would be of interest to monitor the per-oxodisulfate concentration with a maintenance-free and cost-effective electrochemical sensor.
