Abstract

PURPOSE:To quantitatively measure a very small amoung of H2O2 in the order of ppb, by using a detecting element of exygen closely stuck a fixation membrane of decomposition agent of hydrogen peroxide to detecting face and continuously blowing an inactive gas in the liquid to be inspected in order to exclude dissolved oxygen. CONSTITUTION:The fixation membrane 2 of H2O2 decomposition catalyst composed of e.g. catalase or living body microorganism fungus containing catalase, or oxides of iron, manganese, cobalt etc. or organic complex salts, is furnished on detecting face of polarograph type oxygen electrode 1 and the electrode 1 is attached on the side wall of the reaction vessel 3. The base solution 20 of phosphoric acid buffer being suitable for the progress of H2O2 decomposition reaction, is put in the vessel 3 and dissolved oxygen is removed by supplying N2 gas from the inactive gas source 6. Oxygen in the sample 30 is removed by N2 gas preliminarily. H2O2 in the sample is decomposed by the membrane 2 and generating volume of oxygen is detected by the electrode 1 and then, its increased volume is recorded by the recorder 9 and also, increasing velocity is detected through the differentiation circuit 8.
