摘要/Abstract

摘要： 基于室温离子液体无蒸气压、离子强度高且稳定、优良溶解性等特点，实验中采用室温离子液体［bmim］［PF₆］作为吸收液，气相色谱-质谱联用分析测定离子液体富集的苯系物，建立了顶空进样-气相色谱-质谱方法测定苯、甲苯、间二甲苯、邻二甲苯、苯乙烯的最佳分析条件。结果表明离子液体有可能作为空气中苯系物的富集材料。

关键词: 室温离子液体, 顶空-气相色谱-质谱法, 1-丁基-3-甲基咪唑六氟磷酸盐, 苯系物

Abstract: In this study，a typical room temperature ionic liquid 1-butyl-3-methylimi dazolium hexafluorophosphate［bmim］［PF₆］was used as an alternative solvent to determine benzene series in indoor air with headspace gas chromatography mass spectrometry based on its characteristics of lower vapor pressure，higher ionic strength and better solubility. In addition，it was also used to enrich the volatile organic compounds. The best analytical conditions was established in this method. It indicates that ionic liquid is possible to be as the enrichment materials of benzene series in the study.

Key words: room temperature ionic liquid, headspace gas chromatography mass spectrometry, 1-butyl-3-methylimi dazolium hexafluorophosphate, benzene series
