Determination of PAHs in Soil Using Micro-Solid Phase Extraction Couple with Gas Chromatography with Copper Isonicotinate as Sorbent

  • 摘要: 建立了膜保护异烟酸铜微固相萃取的样品前处理方法,并采用气相色谱氢火焰离子化检测器对土壤中的痕量荧蒽(Flt)、苯并[b]荧蒽(BbF)、苯并[k]荧蒽(BkF)、苯并[a]芘(BaP)进行了测定. 考察了水温、萃取时间和超声洗脱时间等对萃取效果的影响. 结果表明:在最佳试验条件下,Flt的检出限为1.0 ng/g;BbF,BkF和BaP的检出限为2.5 ng/g. Flt的线性范围为2.5~500.0 ng/g;BbF,BkF和BaP的线性范围均为12.5~500.0 ng/g. 相对标准偏差(RSD)为4.4%~13.7%(n9). 采用该方法分析了2种实际土壤中的4种多环芳烃,回收率为34%~90%.
