水中氯离子的测定方法及其研究进展

Determination of Chloride Ion in Water and Its Research Progress

离子是水体中常见的阴离子之一,其含量的测定是水质监测的一项重要指标。其浓度过高会使水质变差、危害身体健康、妨碍植物生长、腐蚀管道和设备。随着环境及环保法规要求的日益严格,水中氯离子的测定也越来越受到重视。综述了近年来水中氯离子的测定方法,主要包括滴定法、离子色谱法、分光光度法、电位滴定法、浊度法。介绍了上述方法的测定原理、特点、应用,并对各种方法进行了对比分析。

Chloride ion is one of common ions in water,its content is an important indicator for water quality monitoring. It will lead to bad water quality,harm human health,interfere plant growth,corrode pipeline and equipment when its concentration is high. As the requirement of environment and environmental protection regulations become increasingly strict,more and more attentions are paid to the determination of chloride ion in water. The determination methods of chloride ion in water in recent years are reviewed. It mainly includes titration,ion chromatography,spectrophotometric,potentiometric titration and turbidimetry. The principle,characteristic,applications,comparison and analysis for determination methods of chloride ion in water are discussed.
