摘　　要：用DR/85 0 ,GDY - 10 1和QYJ型三种比色计及 72 30型分光光度计分别对水中不同浓度的ClO2 进行了检测。结果表明 :三种比色计及 72 30型分光光度计的测定结果相互间无显著性差异 (P >0 0 5 )。经过比较 ,GDY - 10 1型比色计具有体积小、重量轻、结构简单、操作方便、价格低等优点 ,更适合于ClO2The performances of DR/850, GDY-101 and QYJ colorimeters were comparatively studied with the chlorine dioxide in different concentrations and test samples. The results show that there is no significant difference between the analytical data obtained by three kinds of colorimeters (P>0 05), and between these data and the data obtained by 7230 spectrophotometer (P>0.05). But the GDY-101 colorimeter has the merits of smaller volume, simpler construction and lower cost.
