摘要
综述环境空气与废气中丙烯酸酯类化合物的控制要求及分析方法。对比了国内外生态环境领域环境空气和废气中丙烯酸酯类化合物的分析方法和管理要求。环境空气和废气中丙烯酸酯类化合物主要采用采样罐/固体吸附剂/气袋采样,低温浓缩/溶剂解吸/热脱附进样/直接进样,可采用非极性/中等极性/强极性色谱柱分离,气相色谱(FID/MS)检测。对比不同的采样及处理方法,采样罐/低温浓缩一般与质谱联用,采样成本较高,灵敏度高,适用于环境空气中样品分析;固体吸附剂-溶剂解吸灵敏度较高,但容易造成二次污染;气袋采样-直接进样方便、简单,但灵敏度较低。可根据实际需要选择不同的采样及分析方法。
The control requirements and analysis methods of acrylate compounds in ambient air and waste gas were summarized.The analytical methods,determination and management requirements of acrylates in ambient air and waste gas in the field of ecological environment at home and abroad were compared.Acrylates in ambient air and waste gas were mainly sampled by sampling tank/solid adsorbent/air bag,low-temperature concentration/solvent desorption/thermal desorption injection/direct injection,and could be separated by non-polar/medium polarity/strong polarity chromatographic column and detected by gas chromatography(FID/MS).Compared with different sampling and pretreatment methods,the sampling tank/low-temperature concentration was generally combined with MS,which had high sampling cost and high sensitivity,and was suitable for sample analysis in ambient air.Solid adsorption-solvent desorption sensitivity is high,but it is easy to cause secondary pollution.Bag sampling-direct injection was convenient and simple,but the sensitivity was low.Different sampling and analysis methods could be selected according to actual needs.
