高铁酸离子阳极形成动力学

摘要/Abstract

摘要： 高铁酸盐的杀菌力强,产物对人体无害,不会引起环境污染,作为工业氧化剂具有很多优点,近年来已用它来代替氯、次氯酸盐、高锰酸盐用于消毒水,已有电解法生产的专利发表,并对它的形成过程进行了研究,但仅限于对总的极化曲线的分析.

Abstract: The kinetic data related to the anodic formation of FeO₄^2- and oxygen evolution on iron and mild steel electrodes in concentrated alkaline solution were obtained by measuring the rate of O₂ evolution. It is found that the two reactions Proceed simutaneously and two tafel regions can be separated. At low current density ∂ψ/∂lgi= 2,303 RT/ (I+β)F, i.e. 0.040V (β=0.5) and the reaction ordor with resPecet to α_OH- is 4 for FeO₄^2- anodic formation and 2 for O₂ evolution. At high current density ∂ψ/∂lgi= 2.303 RT/βF, i.e. 0.120V and the reaction ordor is 2 and 1 for both reactions, resPectively. A mechanism for the two reactions is ProPosed.

Key words: Anodic kinetics, Ferrate ion, Oxygen evolution
