Abstract:

研究调查了广州市各大型超市销售的14个品牌,15种不同香型,共26个盒装空气清新剂中挥发性有机物(VOCs)的成分.通过顶空GC-MS分析获得的结果可以看出各个空气清新剂的成分组成差别较大,即使是相同香型的产品,其中的化合物种类和百分比浓度都不尽相同.定性出94种化合物,包括烯烃18种,醇类15种,醛类14种,酮类4种,醚类5种,酚类1种,酯类25种及其它化合物12种,其中萜类化合物约占总化合物数量的40%.β-月桂烯、罗勒烯、苧烯、苯乙醇、乙酸苄酯、β-蒎烯、β-水芹烯、伞花烃、1-甲基-4-(1-甲基乙烯基)苯、里拉醇等化合物在各种清新剂中出现频率为100%.空气清新剂中萜类化合物与臭氧反应,可生成二次有机气溶胶,对室内空气质量造成影响.
