In this study, a novel amphiphilic magnetic molecularly imprinted polymers (MMIPs) have been prepared by using Fe₃O₄ microspheres as the magnetic core, 4-vinyl pyridine (4-VP) and alkenyl glycosides glucose (AGG) as functional co-monomers. Fe₃O₄ microspheres were directly encapsulated by the polymer without any surface modification in the distillation-precipitation polymerization. The morphology and composition of MMIPs were characterized by X-ray diffraction (XRD), vibrating sample magnetometry (VSM), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Binding property and magnetic separation ability were systematically investigated through the equilibrium binding experiments. The feasibility of magnetic molecular imprinted solid phase extraction (MMISPE) was investigated for the selective enrichment of chloroacetamide herbicides from environmental water samples. The developed MMISPE-HPLC method exhibited good linearity (0.1–200μgL⁻¹), low limit of detection (0.03–0.06μgL⁻¹), and good precision (RSD<7%) under the optimized conditions. The introduced MMISPE-HPLC method was successfully used to analyze chloroacetamide herbicides in environmental water samples. Spiked chloroacetamide herbicides recoveries in three water samples ranged from 82.1% to 102.9%. These results indicated that amphiphilic MMIPs were the promising sorbents for the selective enrichment of chloroacetamide herbicides at trace levels from real environmental water samples.

两亲性磁性分子印迹聚合物从环境水样品中选择性固相萃取氯乙酰胺除草剂。

在这项研究中，通过使用Fe ₃ O ₄微球作为磁核，4-乙烯基吡啶（4-VP）和烯基糖苷葡萄糖（AGG）作为功能性共聚单体，制备了一种新型的两亲磁性分子印迹聚合物（MMIPs）。铁₃ O ₄微球被聚合物直接包封，而在蒸馏-沉淀聚合中没有任何表面改性。MMIPs的形态和组成通过X射线衍射（XRD），振动样品磁力法（VSM），扫描电子显微镜（SEM）和透射电子显微镜（TEM）进行表征。通过平衡结合实验系统地研究了结合性能和磁分离能力。研究了磁性分子印迹固相萃取（MMISPE）从环境水样品中选择性富集氯乙酰胺除草剂的可行性。发达的MMISPE-HPLC方法表现出良好的线性（0.1–200μgL ^-1），低检测限（0.03–0.06μgL ^-1）），并在优化条件下具有良好的精度（RSD <7％）。引入的MMISPE-HPLC方法已成功用于分析环境水样中的氯乙酰胺除草剂。在三个水样中加标的氯乙酰胺除草剂回收率在82.1％至102.9％之间。这些结果表明，两亲性MMIPs是从实际环境水样品中选择性富集微量痕量氯乙酰胺除草剂的有希望的吸附剂。
