应用固相微萃取与高效液相色谱联用技术 (SPME HPLC)分析了环境水样中的痕量 艹屈 。对SPME的条件如萃取时间、萃取温度、离子强度、解吸方式、解吸溶剂、解吸时间和HPLC条件进行了优化 ,建立了SPME HPLC分析环境水样中痕量 艹屈 的方法 ,并将其用于分析自来水、雨水、矿泉水和江水等实际水样。方法的线性范围为 0 0 13μg/L～ 3 0 μg/L ,检出限为 2 7ng/L ,相对标准偏差 (RSD ,n =6 )为 5 6 % ,回收率为 10 3 2 %～ 119 3%。该方法适合于环境水样中痕量 艹屈 的分析 ,体现了SPME在样品前处理中快速、灵敏、简单、无溶剂的特点。
The application of solid-phase microextraction and high performance liquid chromatography coupled with high performance liquid chromatography (SPME HPLC) analysis of environmental water samples trace flexion. The conditions of SPME, such as extraction time, extraction temperature, ionic strength, desorption method, desorption solvent, desorption time and HPLC conditions were optimized. The method of SPME HPLC for the determination of trace 艹 flex in environmental water samples was established and applied to Analyze tap water, rain water, mineral water and river water and other actual water samples. The linear range of the method was 0 0 13μg / L ~ 30μg / L, the detection limit was 27ng / L, the relative standard deviation (RSD, n = 6) was 56% and the recovery was 10 3 2% ~ 119 3%. This method is suitable for the analysis of trace 艹 艹 in environmental water samples, which shows that SPME is fast, sensitive, simple and solvent-free in sample preparation.
