| 摘 要： | 以工业污染场地为研究对象,比较和分析了静态顶空、吹扫捕集和固相微萃取等3种前处理方法对土壤中苯系物的气相色谱检测结果差异.结果表明,静态顶空和吹扫捕集两种方法均可对土壤苯系物进行定性定量分析,固相微萃取因土壤有机污染物对萃取探头造成溶解损害而不能检测.静态顶空法检测苯系物各组分的回收率为95.2%～98.2%,吹扫捕集... |

| Abstract: | In order to ascertain BTEX measurements of soils from industrial contaminated sites,static headspace,purge-and-trap and solid phase microextraction(SPME) combined gas chromatography were selected to determine BTEX in the soils.This method of SPME could not be used to analyze BTEX isomers in soils from highly contaminated sites because the high concentration of organic contaminants eroded the SPME probe head.The recoveries for added standard ranged from 95.2%-98.2% for static headspace-GC and 99.2%-101.3% fo... |
| Keywords: | contaminated site soil BTEX static headspace purge-and-trap |
