MA XinbinSchool of Chemical Engineering and Technology, Tianjin University, Tianjin 300072, ChinaAbstract: Dioctyl phthalate molecularly imprinted macroporous resin(DOP-MIP-D101) was preparedby using macroporous resin D101 as carrier, acrylamide as the functional monomer, ethylene glycoldimethacrylate as crosslinker, and DOP as template molecule, and its structure was characterized binfrared spectroscopy and scanning electron microscone static isothermal adsorptionperformance, kinetic adsorption performance and selective adsorption properties of DOP-MIP-D101 onDOP were studied. Results showed that the adsorption capacity of DOP-MIP-D10I on DOP was betterthan that of NIP-D101 and DOP-MTP-D101, indicating its higher recognition ability to the templatemolecule. Adsorption process of DOP-MIP-D1O1 was consistent with the Freundlich model. Theadsorption of DOP-MIP-D101 on DOP reached equilibrium after about 100minKey words: adsorbent:; molecularly imprinted; dioctyl phthalate; adsorption邻苯二甲酸类増塑剂是最常用的塑料橡胶加废水,其中含有DOP以及浓度较高的邻苯二甲酸盐工助剂,其中邻苯二甲酸二辛(DOP)是邻苯类、邻苯二甲酸和醇等物质,处理难度较大。另外,甲酸酯类增塑剂中最重要的品种,其产销量在各种含有增塑剂的塑料橡胶制品在使用过程中,增塑剂塑料橡胶加工助剂中排列第一,属于通用型增塑剂。容易溶出,进入到环境中,从而污染水体和环境。邻苯二甲酸酯增塑剂的毒性已经被证实,主要有慢日前,对含增塑剂废水的处理方法主要有酸化、絮性的和急性的毒性2,以及致癌、致畸、致突变等多种毒性?,对人类健康造成危害,受到人们的高收稿日期:2016-02-18:修改稿日期:2016-03-28度关注。第一作者:唐志民(1970-),男,博士研究生,高级工程师,研究DOP是经过酯化、中和及精制等生产步骤生方向为功能高分子材料。e-mailzhimin.angdhotmail.com。联系人马新宾,教授,博士生导师,研究方向为録色化学和碳一化工.。 E-mail的,生产过程中(尤其是中和过程)会产生大量的xomatiu.edu.cn
