- W2387756817 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." @default.
