以氯化胆碱（ChCl）和甲基丙烯酸（MAA）为原料制备了深度共熔溶剂（DES），并作为环保型表面活性剂和功能单体。利用密度泛函理论对DES的生成过程和生成自由能（ΔG = -37.225 kcal mol-1）进行了理论计算。在基于分子印迹技术制备左氧氟沙星印迹纳米颗粒（LINs）的过程中，引入了设计的DES （ChCl-MAA）作为一种新型的环保功能单体（MAA为对照组）。使用一系列技术对纳米颗粒进行了表征。将纳米颗粒作为吸附材料用于环境废水中左氧氟沙星的选择性去除。采用高效液相色谱法对吸附材料的选择性去除和吸附能力进行了评价。在介绍DES的基础上，DES-LINs对左氧氟沙星的吸附性能优于普通LINs。该方法操作简单，吸附快，去污效果好。
A deep eutectic solvent (DES) was prepared from choline chloride (ChCl) and methacrylic acid (MAA) and used as an eco-friendly surfactant and functional monomer. The process of producing DES and its free energy of formation (ΔG = -37.225 kcal mol-1) were evaluated theoretically by density-functional theory. The designed DES (ChCl-MAA) was introduced as a novel eco-friendly functional monomer (MAA as the control group) during the preparation of levofloxacin-imprinted nanoparticles (LINs) based on molecular imprinting technology. The nanoparticles were characterized using a range of techniques. The nanoparticles were applied as an adsorbing material to the selective removal of levofloxacin from environmental waste water. The selective removal and adsorption capacity of the adsorbing material were evaluated by high-performance liquid chromatography. Based on the introduction of DES, DES-LINs had better adsorption capacity for levofloxacin than common LINs. This method had the simple operation, rapid adsorption and efficient decontamination.
