采用动态顶空进样,气相色谱/离子阱质谱法测定土壤中的苯系物。对样品的吹扫温度、吹扫时间和解析时间进行了优化,各组分的方法检出限:苯为0.43μg/kg,甲苯为1.13μg/kg,对、间二甲苯均为1.74μg/kg,邻二甲苯为0.37μg/kg;对5种苯系物的低、中质量浓度标液进行加标,回收率为82.0%~115%,重复测定7次的RSD为4.8%~15.1%。对某造纸厂周边土壤样品中苯系物进行测定,结果固废堆存处周边土壤中苯和甲苯检出。
採用動態頂空進樣,氣相色譜/離子阱質譜法測定土壤中的苯繫物。對樣品的吹掃溫度、吹掃時間和解析時間進行瞭優化,各組分的方法檢齣限:苯為0.43μg/kg,甲苯為1.13μg/kg,對、間二甲苯均為1.74μg/kg,鄰二甲苯為0.37μg/kg;對5種苯繫物的低、中質量濃度標液進行加標,迴收率為82.0%~115%,重複測定7次的RSD為4.8%~15.1%。對某造紙廠週邊土壤樣品中苯繫物進行測定,結果固廢堆存處週邊土壤中苯和甲苯檢齣。

A gas chromatography/mass spectrometry coupled with dynamic headspace method was estab-lished for the determination of benzene series in soil .The sweeping temperature ,sweeping time , and desorption time were optimized, and the detection limits were from 0.37 μg/kg~1.74 μg/kg.The low and medium con-centration of blank spike showed the recovery rate were form 82 .0%~115%.The RSDs of seven times′repeti-tive determination ranged from 4 .8%~15 .1%.At the same time , the benzene series in the soil around the pa-per mill were detected using this method and the result was benzene and toluene were detected in the soil around the solid waste piles .
