【摘要】 甲基硅氧烷的产量及消耗量巨大.作为全球环境中的新型污染物,部分甲基硅氧烷已在工业生产中被限制使用.甲基硅氧烷的同系物丰富,存在于多种样品基质中,且含量差异较大.为了更好地表征甲基硅氧烷的污染程度,以评估其对环境和人体健康的可能风险,需要建立准确、灵敏、高效的分析方法.本文系统地综述了国内外有关甲基硅氧烷的样品前处理技术及仪器分析方法,比较了不同方法的优缺点,提出了分析过程中要特别关注的问题,并就未来的研究方向进行了展望.更多还原

【Abstract】 Methylsiloxanes have huge production and consumption. As a new class of pollutants in the global environment, some methylsiloxanes have been restricted in industrial production. The homologues of methylsiloxane are abundant. They exist in a variety of matrixes with large differences in content. To better represent the pollution levels of methylsiloxanes and assess their possible risk to the environment and human health, it is necessary to establish the accurate, sensitive and efficient analysis methods. In this review, pretreatments and analysis methods of methylsiloxanes in multiple sample matrixes were systematically summarized. The pros and cons of different methods were compared, and the problems that should be paid special attention to in analysis procedures were put forward. The prospect of further research direction is also included.更多还原
