将居里点裂解气相色谱-质谱法(Py-GC-MS)与传统的提取方法(索氏提取法、超声提取法、氢氧化钾消解法、微波辅助提取法)和GC-MS法进行了比较，并对污染土壤中多环芳烃(PAHs)进行了分析。在每一种情况下，都对美国环境保护局优先污染物清单中的16种多环芳烃的效率进行了检查。结果表明，多环芳烃的回收率与萃取工艺有关。居里点热解和KOH消解对多环芳烃的回收率最高。PY-GC-MS是测定污染土壤中多环芳烃的一种有趣的替代方法。结果通过认证土壤(CRM104)分析得到了验证。(C)2003爱思唯尔B.V.保留所有权利。
Curie point pyrolysis gas chromatography-mass spectrometry (Py-GC-MS) has been compared with classical extraction procedures (Soxhlet, sonication, KOH digestion, microwave-assisted) followed by GC-MS analysis for the determination of polycyclic aromatic hydrocarbons (PAHs) in contaminated soil. In each case, the efficiency of the technique was examined for 16 PAHs included in the US Environmental Protection Agency Priority Pollutant List. The results indicate that the recovery of PAHs is dependent on the extraction technique. The highest recoveries of PAHs were obtained with Curie point pyrolysis and KOH digestion. Py-GC-MS appeared to be interesting alternative method for the determination of PAHs in contaminated soil. The results were validated by certified soil (CRM 104) analysis. (C) 2003 Elsevier B.V.
