固相膜萃取富集大体积地下水中痕量半挥发性有机污染物
Enrichment of Trace Amount of Semi-Volatile Organic Pollutants from Large Volumes of Ground Water by Extraction with Solid-Phase Membrane
摘 要
研究了用C18固相膜萃取法(SPE)富集大量地下水样中半挥发性有机污染物,试验中以有机氯药(OCP′s)及多环芳烃(PAH′s)作为试验对象的现场采样富集,并以气相色谱-质谱法完成其定性及定量测定.对SPE的多项参数,诸如萃取率、检出限及测定限以及准确度和精密度均作了测试.在与液-液萃取法(LLE)所作的对比试验所得到的结果表明:SPE法的回收率为79.1%~103.7%(OCP′s)和72.4%~119.2%(PAH′s);相对标准偏差为6.4%~16.7%(OCP′s)和3.4%~20.2%(PAH′s).SPE法之优于LLE法主要在于分析过程快速,有机溶剂使用量大大减少,方法更适合于大量水样中有机污染物的现场取样处理.

Abstract
The field-sampling of enrichment of trace amounts of semi volalite organic pollutants,taking organic chlorine pesticides (OCP′s) and polycyclic aromatic hydrocarbons (PAH′s) at testing objects,from large volumes of ground water by extraction with C18-solidphase membrane (SPE) was studied and the determination was concluded by GC-MS.Various parameters of SPE (i.e.the rate of extraction,the limits of detection and determination,the accuracy and precision of the method) were tested.As shown by the results obtained in a comparative study with the method of liquid-liquid extraction (LLE),range of average recoveries for OCP′s were from 79.1%-103.7% and for PAH′s were from 72.4%-119.2%,and the range of RSD′s for OCP′s were from 6.4%-16.7% and for PAH′s were from 3.4%-20.2%.The superiority of SPE over LLE was proved by its speed of analysis,using less organic solvents,and suitable to be used in treatment of large volumes of water sample at the testing ground.
