二氧化氯的分析方法

二氧化氯是一种理想的消毒杀菌剂,世界卫生组织将其安全性列为Al级,已成为国际上公认的氯系消毒剂更新换代产品。但是,在二氧化氯的制备过程中会产生多种副产物,二氧化氯自身也会发生分解和歧化反应产生Cl2、ClO-、ClO3-、ClO2-等物质,它们会削弱二氧化氯在应用中的优势。因此在制备及使用过程中,需要对ClO2及副产物进行分析测定,本文对现有的分析方法进行讨论。

Analysis Methods of Chlorine Dioxide

As a kind of perfect disinfectant, chlorine dioxide＇s safety has been classified as AⅠ-level by World Health Organization, and it has been recognized as updated product of chlorine disinfectant. But In the preparation process of chlorine dioxide, various byproducts will been produced, as well as the self-decomposition and disproportionation reaction of chlorine dioxide will produce Cl2,ClO-,ClO3-,ClO2-,which can seriously weaken the advantage of chlorine dioxide in application.Therefore,it is necessary to analyze chlorine dioxide and its byproducts in production and application. In this paper, analysis methods of chlorine dioxide were discussed.
