浅析利用KI-DPD法检测饮用水中的臭氧

Analysis on the Detection of Ozone in the Drinking Water with KI-DPD Method

简要介绍了测定饮用水中臭氧含量的KI-DPD法,系统考察了该方法的检出限、准确度、精密度、加标回收、干扰试验等,根据实验结果可以看出该方法检测范围广、准确度和精密度良好,试剂及设备成本低,操作简单,水中常见离子对检测结果无影响,可以满足臭氧含量的现场快速测定。

This paper briefly introduces the detection of ozone in the drinking water with KI-DPD method, and systematically investigates the detection limit, precision, accuracy, spike recovery, and interference test, etc. of this method, and based on the test results, points out that this method can satisfy the rapid detection of ozone content in the scene because its detecting range is broader, its precision and accuracy are better, the cost of its reagents and equipment is lower, its operation is more simple, and common ions in water have no influence on the test results.
