摘要
对应用碘量法、直接分光光度法和联邻甲苯胺法测定二氧化氯的方法、特性及适用范围进行的研究表明,碘量法主要用于二氧化氯临时标准溶液的标定;直接分光光度法适用于测定二氧化氯发生器出口含量,控制现场投加量;联邻甲苯胺法则可满足常规的水质检验的要求.
This paper concerned with the analytical approachs,features and extents of iodometry,direct spectrometry and diominoditolyl dye mordant methods for measuring concentrations of chlorine dioxide solutions.The results indicated, the iodometry was suit for measuring standandization chlorine-dioxide concen- trations;direct spectrometry was suit for measuring chlorine dioxide concentra- tions from the generators to control disinfection doses;diominoditolyl dye mor- dant method was suit for general water quality analysis.
