摘　　要：采用CD-WAX毛细管柱和FID检测器,以正癸烷为内标物,建立了苯、甲苯、乙苯、对二甲苯、间二甲苯和邻二甲苯等6种苯类溶剂同时测定的气相色谱分析方法。苯、甲苯、乙苯、对二甲苯、间二甲苯和邻二甲苯的标准偏差为0.0024~0.1720,变异系数为0.61%~2.96%,线性相关系数为0.9987~0.9998,6种成分4个水平的添加回收率为97.97%~101.77%。该法分离效果好、准确度高、重现性好且操作简单快速。A gas chromatography method was developed for simultaneous determination of benzene,methylbenzene,ethylbenzene,p-xylene,m-xylene,o-xylene on CD-WAX capillary column with FID detector.The results showed that the linear correlation coefficients of benzene,methylbenzene,ethylbenzene,p-xylene,m-xylene,o-xylene were0.998 7-0.999 8,the variation coefficients were 0.61%-2.96%,and the fortified recoveries were 97.97%-101.77%.The method had such advantages as good separation,excellent repeatability,high accuracy,etc.
