| 摘 要： | 建立顶空气相色谱法测定生活饮用水中微量苯系物的方法,各组分的分离度较好.苯、甲苯、乙苯、对二甲苯、间二甲苯、邻二甲苯、异丙苯的检出限分别为0.002、0.004、0.005、0.007、0.007、0.008、0.005 mg/L,样品的平均加标回收率为97.0%～100.8%,测量结果的相对标准偏差不大于5.1%(n=5),该方法可满足水中苯系物的检测要求.

| Abstract: | The method for determining benzene series in drinking water by headspace gas chromatography was established. Each component was in better separation. The detedction limits for benzene,toluene,ethylbenzene,p-xylene,m-xylene,o-xylene,cumene were 0.002,0.004,0.005,0.007,0.007,0.008,0.005 mg/L respectively. The average recoveries were 97.0%-100.8%,and the RSDs were no more than 5.1%(n=5). The method can meet the testing requirements of benzene series in drinking water. |
