Summary:PROBLEM TO BE SOLVED: To oxidize/decompose oxidizable pollutants efficiently and to extend the life of electrodes by using an electrode having a liquid-contact part comprising a mixed layer of platinum and iridium as an anode. SOLUTION: A specimen water tank 1 and an electrolytic bath 2 are installed adjacently, and an anode 3 and a cathode 4 are formed in the electrolytic bath 2. Water containing oxidizable pollutants and an inorganic chloride is electrolyzed by using an electrode having a liquid-contact part comprising a mixed layer of platinum and iridium as the cathode 3. The electrode for electrolyzing the pollutants-containing water has the liquid-contact part comprising platinum and iridium. The form of the mixed layer is not restricted in particular, and for example, the layer comprises a platinum-iridium alloy, or platinum portions and iridium portions are dispersed in the layer. As the oxidation-reactive pollutants, organic compounds in general and inorganic compounds such as ammonia and hydrazine can be named.
