A novel NH2-MIL-88B(Fe)-modified ceramic membrane for the integration of electro-Fenton and filtration processes: A case study on naproxen degradation

Process intensification based on innovative coupling between membrane microfiltration and catalytic oxidation technologies has become a promising strategy for water treatment. Here, surface-nucleated metal–organic framework (MOF) was grown in situ to obtain an NH2-MIL-88B(Fe)-functionalized ceramic (NH2-MIL-88B(Fe)@CM), whose ability remove naproxen from matrices via the so-called electro-Fenton with (EFCCM) process systematically investigated. The physicochemical properties of NH2-MIL-88B(Fe) membranes were characterized by XRD, FTIR, XPS SEM, revealing formation well-defined layer porous CM thickness around 13.5 µm, which provides large amount active sites H2O2 activation generate hydroxyl radical (OH). EFCCM treatment Na2SO4 solution under recirculation batch mode yielded almost complete drug removal 90 min at 50 mA, whereas stability catalyst loss tests gave evidence good reusability 5 cycles. urban wastewater confronted severe fouling, but this effectively mitigated combining hot backwash EF self-cleaning. Finally, degradation routes involving 7 byproducts are proposed. This is effective approach fabrication CCM, could be used continuous as suggested minimal NPX content outlet.
