摘　　要：以化学键合三维铁基金属有机框架材料MIL-101(Fe)的蚀刻不锈钢纤维作为固相微萃取(SPME)吸附剂,通过与毛细管电泳(CE)联用,建立了水中苯胺类化合物的SPME-CE分析方法。将所建立的方法用于自然水体中的苯胺类化合物的测定,该方法的线性相关系数为0.9844~0.9974,检出限(S/N=3)为0.52~0.65 mg/L,日内和丝间的相对标准偏差为4.5%~6.7%和4.3%~7.3%。将建立的方法用于水中苯胺类化合物的测定,回收率为96.43%~99.88%。A SPME-CE analysis method for aniline compounds in water was established using etched stainless steel fibers chemically bonded to a three-dimensional iron-based metal organic framework material MIL-101(Fe)(Materials of Institute Lavoisier-101(Fe))as a solid-phase microextraction(SPME)adsorbent.The established method was applied to the determination of aniline compounds in natural water bodies.The linear correlation coefficient of the method was 0.9844~0.9974,the detection limit(S/N=3)was 0.52~0.65 mg/L,and the relative standard deviation within and between days was 4.5%~6.7%and 4.3%~7.3%.The established method was applied to the determination of aniline compounds in water,with a recovery rate of 96.43%~99.88%.
