| 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。
