摘　　要：二氧化氯因其高效、安全、不易产生氯代有机消毒副产物等"三致"物质等优点而替代液氯广泛应用于饮用水、污水处理、食品加工等领域,被誉为第四代消毒剂,是世界卫生组织和世界粮农组织推荐的A1级广谱、安全和高效消毒剂。报道了最近20年来关于二氧化氯的检测方法,主要包括碘量法、电流滴定法、分光光度法、荧光光度法、色谱法、电化学法、生物化学法等,概述了各种方法的优缺点及使用情况。在此基础上,提出了今后的研究方向。Due to the high efficiency, safety, and having no harmful disinfection by-products, chlorine dioxide has widely been applied to the fields of the drinking water, wastewater treatment and food processing. Chlorine dioxide is named as the fourth generation of disinfectant which is recommended by the World Health Organization and International Food and Agriculture Organization. The analytical methods mainly including iodometry, amperometric titration, spectrophotometry, fluorimetry, chromatography, electrochemistry, biochemistry, etc., which were published in the last twenty years, on the determination of chlorine dioxide are reported. Their merit, demerit and applied situation are summarized, and the future research direction of the chlorine dioxide determination is prospected.
