DECOMPOSITION METHOD AND DEVICE PROVIDED WITH ADSORPTION ELECTRODE

摘要

PROBLEM TO BE SOLVED: To efficiently decompose while avoiding the secondary environmental pollution due to the compd. formed resulting from decomposition by adsorbing a subject material to be decomposed to an electrode and also decomposing the subject material to be decomposed under photoirradiation by using the functional water generated near the electrode by electrolysis. SOLUTION: An ion exchange membrane 13 is provided at the inside of a decomposition tank main body 11 consisting of a light-transmissive material such as glass. An adsorption electrode 12 consisting of an electrically conductive adsorptive material is disposed similarly and connected at the positive electrode side of a power source device 18 and used as an anode at the time of electrolysis. Moreover, a cathode 16 consisting of platinum or the like is disposed at the reverse side to the adsorption electrode 12 and connected at a negative electrode side of the power source device 18. Then the subject material to be decomposed is charge from a bubbler 15 disposed at the lower part of the adsorption electrode 12 immersed in an aq. soln. containing electrolyte and adsorbed to the electrically conductive adsorptive material in the adsorption electrode 12. Thereafter, light is applied from a light irradiation means 14 and simultaneously the electrolysis is executed by charging the power source of the power source device 18 to form the functional water and to decompose the material.
