摘要
本文提出了一种退色型间接分光光度法测定水中二氧化氯含量的方法。在ｐＨ＝１．Ｏ士０．５时，二氧化氯与甲基橙－溴化钾溶液发生退色反应，其浓度与吸光度在０．０４～０．５０ｍｇ／Ｌ的检测范围内呈极显著的线性相关（ｒ＝０．９９９８），方法灵敏度为０．０４ｍｇ／Ｌ。本法具有简单、快速、实用等特点。
In this paper,a method for the determination of ClO2 in water was proposed ,by using a in-direct spectrophotometry of bleaching type. At pH=1.O士0.5, ClO2 can react bleaching-outlywith solution of methyl orange-potassium bromide. Its concentration and the absorbance arefairly correlated within 0.04～0. 50mg/L(r=0.9998).The sensitivity of the method is0.04mg/L.
