吹扫捕集-气相色谱-质谱法测定加油站地下水中特征污染物
Determination of Characteristic Pollutants in the Groundwater of Gas Stations by Purge and Trap-GC/MS
摘 要
采用吹扫捕集-气相色谱-质谱法同时测定加油站地下水中特征污染物甲基叔丁基醚、苯、甲苯、乙苯、二甲苯和萘含量.水样经吹扫捕集浓缩仪处理后,采用HP-5MS型毛细管色谱柱分离,质谱中选择电喷雾离子源-全扫描模式,以氟苯和1,2-二氯苯-D4为内标进行定量.7种化合物的质量浓度在一定范围内与其峰面积呈线性关系,检出限(3S/N)为0.1~0.4 μg·L-1.加标回收率在91.0%~105%之间,测定值的相对标准偏差(n=6)在1.1%~3.9%之间.

Abstract
The content of characteristic pollutants,including methyl tertiary butyl ether,benzene,toluene,ethyl benzene,p-xylene,m-xylene,o-xylene,and naphthalene,in the groundwater of gas stations were determined by Purge and Trap-GC/MS. The water sample was treated by a purge-trap concentrator and then separated on a HP-5MS capillary column. EI and full scan were adopted in MS. Fluorobenzene and 1,2-dichlorobenzene-D4 were used as internal standards for quantification. The linear relationship between the peak area and the mass concentration of the seven compounds was in a certain range,with detection limits in the range of 0.1-0.4 μg·L-1. The recovery rates measured by standard addition method were in the range of 91.0%-105%,with RSD in the range of 1.1%-3.9%
