色谱法检测样品中残留丙烯酸的研究进展

Research Progress on Chromatographic Determination of Residual Acrylic Acid in Samples

丙烯酸是一种重要的化工原料,在危险废物鉴别标准中被列为剧毒物质。国家标准列出了工作场所、食品、饮用水等环境中丙烯酸的限制浓度,但是对于丙烯酸的定量检测方法没有统一的规定,尤其是水体和固废中。本文综述了目前仪器分析中常见的丙烯酸的定量检测方法,针对不同形态样品,对比各种检测方法的差异。色谱法是丙烯酸检测常用的方法,不同形态的样品适合不同的分析方法。液相色谱法目前是检测丙烯酸最实用的方法。

Acrylic acid is an important chemical raw material.In the hazardous waste identification standard,acrylic acid is included in the highly toxic substances.The national standard lists the limitation concentration of acrylic acid in workplaces,food and drinking water environment,but there is no uniform regulation for the quantitative detection method of acrylic acid,especially in water and solid waste.The common detection methods of acrylic acid in instrumental analysis were reviewed,and the differences of various detection methods were compared according to different sample states.Chromatography was a common method to detect acrylic acid.Different forms of samples were suitable for different analytical methods.Liquid chromatography was the most practical method for the detection of acrylic acid.
