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 FeO42- 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 αOH- is 4 for FeO42- 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
