摘　　要：本文采用气相色谱-质谱联用法,检测了轻质油品中的二茂铁、甲基环戊二烯三羰基锰、环戊二烯三羰基锰、四乙基铅这4种金属抗爆剂。采用5%-二苯基-95%二甲基聚硅氧烷石英毛细管柱,实现了4种金属抗爆剂的有效分离。采用内标法定量,4种金属抗爆剂在0~50mg·L^-1范围内线性关系良好,线性相关系数均达到0.999,各金属抗爆剂的检出限均低于0.1mg·L^-1,加标回收率在96.7%~110.0%之间,各标准浓度的相对标准偏差均小于2.0%。该方法操作简单,准确高效,是测定轻质油品中金属抗爆剂的有效方法。Four metal antiknock agents of cyclopentadiene manganese tricarbonyl,methylcyclopentadienyl manganesetricarbonyl,ferrocene and tetraethyllead in lightweight oil were determined by GC-MS.Applied quartz capillary column of 5%-diphenyl-95%dimethyl polysiloxane,four metal anti-knocking agents in a lightweight oil were successfully separated.Internal standard method was applied for quantification.The linear range of the four metal antiknock agents was 0~50 mg/L,all of the linear correlation coefficient were 0.999,all of the minimum quantitative detection limit were below 0.1 mg/L,the recoveries were 96.7%~110.0%.The relative standard deviation of each standard concentration was less than 2.0%.
