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.
一种由氯化胆碱（ChCl）和甲基丙烯酸（MAA）制备的深共晶溶剂（DES）被用作环保型表面活性剂和功能单体。通过密度泛函理论对 DES 的制备过程及其生成自由能（ΔG = -37.225 kcal mol-1）进行了理论评估。在基于分子印迹技术制备左氧氟沙星印迹纳米粒子（LINs）的过程中，将设计的 DES（ChCl-MAA）作为一种新型环保型功能单体（以 MAA 作为对照组）。采用多种技术对纳米粒子进行了表征。将纳米粒子用作吸附材料，用于从环境废水中选择性去除左氧氟沙星。通过高效液相色谱法评估了吸附材料的选择性去除和吸附容量。基于 DES 的引入，DES-LINs 对左氧氟沙星的吸附容量优于普通 LINs。该方法具有操作简单、吸附速度快、净化效率高的特点。
