Persistence Study on Gasoline Compound in Soil Matrix and its Application in Fire Investigation

Adsorptivity of gasoline attached on soil matrix was discussed. Peak areas’ changing trend of target compounds’ and typical compounds of gasoline were proposed, by fitting peak areas and time. Results shown that retention times of different compounds in gasoline attached on soil were different. C5 alkylbenzene, Naphthalene and Methylnaphthalene had the longest retention time, next come indane and C4 alkylbenzene. C1, C2 and C3 alkylbenzenes have the shortest retention time.
