In this work, a magnetic molecularly imprinted chitosan membrane (MMICM) was synthesized for the extraction of chlorobenzene compounds in environmental water using the membrane separation method. The optimal extraction amount for chlorobenzene (9.64 mg·L) was found to be a 1:2 solid to liquid ratio, with a 20 min extraction time and 35 °C extraction temperature. This method proved to be successfully applied for the separation and trace quantification of chlorobenzene compounds in environmental water, with the limit of detection (LOD) (0.0016-0.057 ng·L), limit of quantification (LOQ) (0.0026-0.098 ng·L), and the recoveries ranging (89.02-106.97%).
在本研究中，合成了一种磁性分子印迹壳聚糖膜（MMICM），用于采用膜分离法提取环境水中的氯苯类化合物。发现氯苯的最佳提取量为9.64 mg·L，固液比为1:2，提取时间为20分钟，提取温度为35℃。该方法被证明可成功应用于环境水中氯苯类化合物的分离和痕量定量，检测限（LOD）为0.0016 - 0.057 ng·L，定量限（LOQ）为0.0026 - 0.098 ng·L，回收率在89.02% - 106.97%之间。
