Abstract

Abstract: Dioctyl phthalate molecularly imprinted macroporous resin (DOP-MIP-D101) was prepared by using macroporous resin D101 as carrier, acrylamide as the functional monomer, ethylene glycol dimethacrylate as crosslinker, and DOP as template molecule, and its structure was characterized by infrared spectroscopy and scanning electron microscope. The static isothermal adsorption performance, kinetic adsorption performance and selective adsorption properties of DOP-MIP-D101 on DOP were studied. Results showed that the adsorption capacity of DOP-MIP-D101 on DOP was better than that of NIP-D101 and DOP-MIP-D101, indicating its higher recognition ability to the template molecule. Adsorption process of DOP-MIP-D101 was consistent with the Freundlich model. The adsorption of DOP-MIP-D101 on DOP reached equilibrium after about 100min.

摘要： 以大孔吸附树脂D101为载体,丙烯酰胺为功能单体,乙二醇二甲基丙烯酸酯为交联剂,邻苯二甲酸二辛酯(DOP)为模板分子,制备了DOP分子印迹吸附树脂(DOP-MIP-D101),采用红外和扫描电镜等方法对其进行了表征。研究了DOP-MIP-D101对DOP的静态等温吸附性能、吸附动力学以及选择性吸附性能。结果显示,DOP-MIP-D101对DOP的吸附能力明显大于非印迹树脂(NIP-D101),且具有较高的选择性,吸附行为符合Freundilich方程。DOP-MIP-D101对DOP的吸附达到平衡的时间为100min左右。
