离子色谱法测定环境空气和废气中氯化氢的问题探讨

Discussion on Determination of Hydrogen Chloride in Ambient Air and Stationary Source Emissions by Ion Chromatography

离子色谱法测定环境空气和废气中氯化氢较其他方法如硫氰酸汞分光光度法、硝酸银容量法等有所用试剂少、二次污染小、选择性好、准确灵敏、分析操作简单等优点,在环境监测领域得到广泛的应用,技术也日趋成熟。但在实际的应用过程中仍然存在一些需要注意的问题。本文从样品采集、分析测试两个方面对离子色谱法测定空气和废气中的氯化氢进行探讨,分析实际的应用过程中需要注意的问题,并提出合理化建议。

Compared with other methods such as mercuric thiocyanate spectrophotometric method and silver nitrate titration,ion chromatography has the advantages of less reagents,less secondary pollution,good selectivity,accuracy and sensitivity,simple analysis operation,and so on,which has been widely used in the field of environmental monitoring,and the technology has been becoming more and more mature.However,there is still some problems that needs to be paid attention to in the actual application process.The determination of hydrogen chloride in ambient air and stationary source emissions by ion chromatography was discussed,which based on sample collection,analysis and test.The problems in practical application were analyzed,and reasonable suggestions were put forward.
