| 摘 要： | 本实验首次合成了以金属有机骨架MIL-88A作为前驱体,采用分子印迹法改性后的催化剂MIL-88A@MIP,并通过X射线衍射仪(XRD),扫描电镜(SEM)以及EDS能谱和氮气吸附对催化剂进行表征分析.以造纸废水中邻苯二甲酸二丁酯(DBP)作为目标污染物,探究该催化剂活化过硫酸盐(PS)产生SO_4~-·的能力.对比前驱体MIL-88A,靶向改性有效地提高了MIL-88A@MIP的催化活性,在反应480 min后,DBP的去除率高达80.4%.影响因素实验表明该催化剂的最佳活化条件为:PS∶DBP=600∶1、MIL-88A@MIP投加量0.5 g·L~(-1)、体系中pH为3.26.此外,探究了MIL-88A@MIP对于催化PS降解不同污染物的能力,其结果表明该催化剂对于邻苯二甲酸酯类(PAEs)物质均有降解效果,体现了其靶向选择性.

| Abstract: | MIL-88A@MIP was fabricated for the first time in this experiment with a metal-organic framework of MIL-88A as the precursor based on the molecular imprinting method. It was characterized by X-ray diffraction (XRD), scanning electronic microscopy (SEM), energy dispersive spectrometer (EDS), and N2 adsorption. The catalytic performance of MIL-88A@MIP was tested to activate persulfate (PS) to generate SO4-· for the degradation of dibutyl phthalate (DBP), which was used as a target pollutant. Compared with the precursor MIL-88A, the catalytic activity of MIL-88A@MIP was improved effectively through targeted modification, and the DBP removal rate increased 80.4% after reacting for 480 min. An experiment determining the influencing factors showed that the optimum activation condition of the catalyst was PS:DBP=600:1, MIL-88A@MIP dosage of 0.5 g·L-1,and pH=3.26. Furthermore, MIL-88A@MIP shows a high capability of removing different phthalic acid ester (PAE) contaminants that reflect its targeting selectivity. |
