摘要
采用紫外分光光度法，于二氧化氯有特征吸收峰的 ２６０ｎｍ波长下测定溶液中二氧化氯含量。对二氧化氯含量＜３００ ｍｇ／Ｌ的溶液，测定结果的相对标准偏差≤５．０９％。样品溶液ｐＨ值在５～１０与放置时间≤５０ ｍｉｎ时，对测定结果影响不大。
Ultraviolet spectrophotometry was used to measure chlorine dioxide content in solution at wavelength of 260 nm which is the characteristic absorption peak of chlorine dioxide. The relative standard deviation of measured results of the solution containing chlorine dioxide ≤ 300mg / L was ≤5.09%. When the pH value of the sample solution was 5-10 and the solution was laid aside for ≤5 min, there was no significant influence on measured results.
