应用便携式比色计测定水中ClO_2残留浓度

Determination of chlorine dioxide residue by portable colorimeter

研制适合水中CIO_2残留浓度测定的HK-便携式CIO_2(LR)比色计,并与传统分光光度法对CIO_2测定结果的进行比较,结果表明2种测定方法的结果一致,HK-便携式CIO_2(LR)比色计可在现场准确、快速测得结果。本文还探讨测定过程中的影响因素。

In this paper, HK portable colorimeter（CIo2, LR）was designed for determination of chlorine dioxide residue in water, Chlorine dioxide was determined by f spectrophotometry and HK potable Colorimetcr（CIO2, LR）respectively. The results determined by two methods were accordant. HK portable colorimeter（CIO2）can determine CIO2 exactly and quickly on site, The influence factor during determination was researched too.
