水中微量挥发性有机硫化物是我国饮用水中重要的嗅味物质组成部分,不仅嗅阈值很低,而且具有毒性。水中微量含硫类致嗅物质的分析测试技术是开展各项相关研究的基础,因而受到越来越多的关注。本文介绍了水中常见含硫类致嗅物质的嗅味特征、水中微量挥发性有机硫化物分析测试中遇到的主要困难及主要分析测试方法。气相色谱技术是测试该类物质的实用技术,本文从检测器的选择、色谱柱的选择和预富集方法三个方面详细介绍了采用气相色谱分析水中微量挥发性有机硫化物过程中遇到的主要问题和解决方法,并展望了水中微量挥发性有机硫化物分析测试技术的发展方向。 Micro-volatile organic sulfide in water is an important component of olfactory substances in drinking water in our country. It not only has a low odor threshold, but also is toxic. Analysis and testing technology of trace sulfur-containing odor substances in water is the basis for carrying out various related researches and therefore attracts more and more attention. This paper introduces the olfactory characteristics of common sulfur-containing olfactory substances in water, the main difficulties encountered in the analysis of trace amounts of volatile organic sulfides in water and the main analytical methods. Gas chromatography is a practical technique to test this kind of material. In this paper, the methods of gas chromatography for the analysis of micro-volatile organic sulfur compounds in water are introduced in detail from the aspects of detector selection, column selection and pre-enrichment methods. Main problems and solutions, and prospects of the development of trace volatile organic sulphides analysis and testing technology in water.
