  • 摘要: 以邻苯二甲酸二（2-乙基）己酯为模板分子、甲基丙烯酸为功能单体和乙二醇二甲基丙烯酸酯为交联剂，在TiO2表面合成DEHP分子印迹聚合物，制备了分子印迹型TiO2（MIP-TiO2），优化了制备工艺条件。利用傅里叶红外光谱（FI-IR）和X-射线衍射（XRD）对MIP-TiO2进行表征，并考察了MIP-TiO2对DEHP的光催化降解性能。结果表明，MIP-TiO2的最佳制备工艺条件为模板分子、单体、交联剂和TiO2的摩尔比为1：4：10：1.875，反应温度为60 ℃；聚合时间为18 h。MIP-TiO2仍保持了和TiO2一样的锐钛矿型结构，对DEHP 的光催化效果明显高于TiO2，对浓度为5 mg·L-1的DEHP的光催化降解效率可达88.15%。
    Abstract: Molecularly imprinted TiO2(MIP-TiO2) was prepared by using TiO2 as support, Di(2-ethylhexyl) phthalate(DEHP) as template, MAA as functional monomer, EGDMA cross-linker, respectively.Preparation conditions were optimized.The prepared MIP-TiO2 was characterized by Fourier transform infrared spectroscopy (FT-IR) and X-ray diffraction (XRD).The photocatalysis properties of the prepared MIP-TiO2 for Di(2-ethylhexyl) phthalate were investigated.The results indicated that the optimum process condition for preparation of MIP-TiO2 was as follow:molar ratio of template molecules-to-monomer-to-crosslinking agent-toTiO2 of 1:4:10:1.875, reaction temperature of 60℃ and polymerization time of 18 h.MIP-TiO2 existed in the identical anatase phase as TiO2.Moreover, MIP-TiO2 showed significantly high photocatalytic activity compared to TiO2.The degradation rate of DEHP with initial concentration of 5 mg·L-1, catalyzed by MIP-TiO2 under UV-light irradiation, could reach 88.15%.
