摘要
该文研究了土壤基质对汽油的吸附性,得出了汽油的总离子峰面积在土壤基质上的变化趋势以及汽油中的不同组分在土壤基质上的变化规律。通过对汽油中目标化合物和典型特征化合物离子色谱峰面积与时间的关系进行拟合分析,得出了汽油目标化合物和特征化合物的时效性拟合曲线。结果显示,汽油中的不同组分在基质中的保存时间不同,C5烷基苯,萘及其取代物的保存时间最长,其次是茚满和C4烷基苯,C1、C2和C3烷基苯的保存时间最短。
Abstract： The absorption property gasoline attached on soil matrix was studied. The relationship be- tween peak areas and target/typical compounds of gasoline was obtained by fitting peak areas and time. The result showed that retention times of these compounds in gasoline attached on soil were different. The retention times of C5 alkylbenzene, naphthalene and methylnaphthalene were longer than those of indane and C4 alkylbenzene. In comparison, the retention times of C1, C2 and C3 alkylbenzenes were shortest.
