中文摘要：

建立了简单、快速、灵敏测定水环境中的双酚A（BPA）、辛基酚（OP）、壬基酚（NP）的方法。以聚（N-乙烯基咪唑-二乙烯基苯）整体材料为涂层的搅拌棒固相萃取技术富集目标物,然后与高效液相色谱-二极管阵列检测器联用测定水样品中烷基酚类污染物。考察了萃取时间、解析时间、样品基质的pH值、离子强度等实验条件对萃取效率的影响。在最佳条件下,3种目标化合物的线性范围是1.0～200μg/L,检出限LOD（S/N=3）在0.13～0.66μg/L之间,定量限LOQ（S/N=10）在0.44～2.19μg/L之间。在对海水和污水处理厂的实际水样测定中,3种目标化合物的不同加标水平的回收率为37.8%～101.1%。本方法具有简便、快速、高效、灵敏等优点。

英文摘要：

A method for the determination of bisphenol A,octyphenol,nonylphenol in water samples was developed using stir bar sorptive extraction（SBSE） based on poly（vinylimidazole-divinylbenzene） monolithic material（SBSEM） combined with high performance liquid chromatography with diode array detection.To achieve the optimum extraction performance,several main extraction parameters,including extraction and desorption time,pH value and contents of inorganic salt in the sample matrix,were investigated.Under the optimized experimental conditions,the method showed good linearity and repeatability,low detection limits （S/N=3） and quantification limits（S/N=10） of the proposed method for the target compounds were achieved within the range of 0.13-0.66 and 0.44-2.19 μg/L,respectively.The extraction performance of SBSEM to the target compounds was also compared with commercial SBSE which used polydimethylsiloxane as coating.The proposed method was successfully applied to the determination of the target compounds in water samples.The recoveries of spiked target compounds in real samples ranged from 37.8%-101.1%.The results indicated that the developed method possessed advantages such as sensitivity,simplicity,low cost and high feasibility.
