Nonconsumable electrode for electrolysis. (Osaka Soda Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 58136790 A2 13 Aug 1983 Showa, 6 pp. (Japanese).Some commonly used reagents like 11129-60-5 and 12030-49-8 are used in this experiment. (Japan). CODEN: JKXXAF. CLASS: IC: C25B011-10. APPLICATION: JP 82-17860 5 Feb 1982. DOCUMENT TYPE: Patent CA Section: 72 (Electrochemistry) A nonconsumable electrode for various types of electrolysis is obtained by coating a valve metal substrate with a rutile-structure possessing Pt-IrO2 (mixt.) 1st layer and a 2nd layer consisting of a mixt. of Mn oxide contg. MnOx (1.5 < x < 2.0) 2.50 and rutile 50-98%. .

DOCUMENT TYPE: Journal CA Section: 72 (Electrochemistry) Alk. mixed solns. of NaClO and NaClO2 at low concns. were electrolyzed at 30° on Ti electrodes coated with oxides of noble metals, Ti/RuO2, Ti/IrO2, and Ti/PdO. Anodic products were analyzed by both UV absorption spectrometry and titrn. with permanganate. Prolonged electrolyses for 28 h of solns. with various concn. ratio of NaClO2 to NaClO at 0.65 V vs. a Hg/HgO ref. electrode on Ti/RuO2 and Ti/IrO2 and 0.70 V on Ti/PdO resulted in a const. concn.There are some commonly used reagents with their cas registry numbers 1314-08-5 and 12030-49-8 in this article. ratio cClO2-/cClO- in the anolyte of 0.11, 0.09, and 0.09, resp. It is suggested that the anodic oxidn. of ClO- at low concns. proceeds by a consecutive 1st order reaction, ClO- ? ClO2- ? ClO3-. .
