摘要：
The solid-phase microextraction (SPME) combined with gas chromatography/mass spectrometry (GC/MS) was used to determine and analyze organic pollutants in coking wastewater.Based on the fact that the main compounds in the wastewater were organics, some key parameters of the SPME were optimized.The method has good linearity (its correlation coefficients>0.99) in the range determined,its relative standard deviations (RSD) are less than 15%,and its recovery is from 87.9% to 128.1% with the lowest quantification limit of 5 μg/L.This method has been used to measure 15 organic pollutants in wastewater from a certain coking plant.The results show that compared with the conventional method,it can save an hour in pretreatment time.It is a fast,low-cost,accurate,simple and efficient analytical method indeed.
