摘要
建立了吹扫捕集与气相色谱一质谱联用测定饮用水中6种苯系物的分析方法。该方法的加标回收率在90%～110%之间,相对标准偏差基本小于5.0%,该方法灵敏度高、准确度好,已成功地用于饮用水中,苯系物的测定,结果令人满意。
An analytic method of purge and trap concentration with gas chromatography and mass spectromentry (GC/MS) was established for determination of 6 kinds of benzene compounds in drinking water.The recovery ratios of the method were 90%～110%,and relative standard deviations(n=7) were generally lower than 5.0% for 30μg/L standard benzenes.This method is sensitive and accurate.The applcation of the method to the determination of benzenes in real sample of drinking water was tested and satisfactory results were obtained.
