饮用水中二氧化氯及其无机消毒副产物的检测技术研究

摘要

饮用水的消毒技术及其副产物一直受到广泛的关注,文章重点介绍了国外饮用水中二氧化氯和其无机消毒副产物检测技术以及在中国应用状况.二氧化氯的检测方法有很多种,包括碘量滴定法、紫外分光光度法、荧光光度法、电流滴定法、离子色谱法等.在众多二氧化氯分析方法中,五步碘量法、连续五步碘量法和紫外分光光度法的应用最为广泛.%The disinfection of drinking water technology and its by-products has received widespread attention. The article mainly introduces the abroad of chlorine dioxide in drinking water disinfection by-products and its inorganic detection technology and application status in China. There are many kinds of test method for chlorine dioxide, including iodine titration method, UV spectrophotometry, fluorescence spectrophotometry, current titration method, ion chromatography, etc. In many analysis methods of chlorine dioxide, five steps, for five consecutive steps by iodine volume method and by iodine volume method and the applica-tion of UB spectrophotometry is more extensive.
