| 摘 要： | 本文通过大量的实验确定了用甲酚械示差光度法定量测定二氧化氯的实验条件。该方法操作简便，选择性强，分析速度快，准确度与灵敏度都比较高。最低检出限为４．１ｐｐｂ，测定上限１．３５５ｐｐｍ，变异系数５．３５％，是测定饮用水中低含量二氧化氯的一种行之有效的方法。

| Abstract: | In this paper conditions of determination of ClO2 by using cresol red-differential spectrophotometry have been investigated on the basis of numerous experiments. The method has simple, accurate and sensitive etc. advantages. The minimum detection level is 4.1ppb, CV is 5.35%. It is a practicable and available method for determination of low consentration of ClO2 in potable water. |
