[MIL-88A@MIP Activated Persulfate for Targeted Degradation of Dibutyl Phthalate].

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 N adsorption. The catalytic performance of MIL-88A@MIP was tested to activate persulfate (PS) to generate SO 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,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.
