Dye removal from wastewater is an application for which membrane hybrid processes are widely applied. The focus of this study is also on development of a membrane hybrid process for dye removal from wastewater. Different proportions of NH2-MIL125(Ti) were embedded in a PSf polymeric membrane through the phase inversion method and the membrane performance was evaluated for the degradation of a Methylene Blue dye under three different light conditions of dark environment, UV and visible light irradiation. The synthesized membranes were characterized by FTIR, XRD, and FE-SEM measurements. NH2-MIL125(Ti) nanoparticles were successfully entrapped in the PSf membrane through a simple phase inversion method and addition of NH2-MIL125(Ti) to the PSf membrane resulted in the improvement of membrane porosity. Up to 60% of dye degradation was observed with the 1% NH2-MIL125(Ti)/PSf nanocomposite membrane after 300 minutes of UV light irradiation. Degradation kinetics followed a pseudo first order model, evidence of possible changes in the membrane properties upon irradiation with simulated solar radiation.
