Abstract

PURPOSE:To measure the concentration of O3 in waste water accurately and rapidly, by forming a filter made by a porous inorganic compound and dispersed an ozone decomposition agent as an ozone decomposition membrane on an oxygen permeable membrane of an oxygen detector having the oxygen permeable membrane. CONSTITUTION:An ozone electrode provided an ozone decomposition membrane 8 made by an activated carbon nonwoven fabric or a porous inorganic compound filter dispersed a powdered ozone decomposition agent such as Ni, Mn, Cu on an oxygen permeable membrane 4, is prepared. An electrolyte 3, an oxygen reduction electrode mades of platinum 5 and an opposite electrode made of silver 6, are put in a cylindrical support 2 of the electrode 1 and the membrane 4 and 9 are sealed hermetically by a cap 10 of the tip end part of the support 2 by using on O ring 9. The electrode 1 is immersed in an O3 dissolved solution and generated O3 and dissolved O2 are passed through the membrane 4. Then, the current value produced by reducing the sum of both O2 by the pole 5 and that of by O2 in the O3 dissolved solution separately, are measured and the O3 concentration is measured accurately by the difference of both values.
