Preparation and characterization of TiO2-LaFeO3 based mixed matrix membrane for oily wastewater treatment

The aim of this study was to investigate the effects of catalyst loading in mixed matrix membrane. LaFeO3 and TiO2-LaFeO3 were synthesized by sol-gel glucose method. Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), contact angle, membrane permeation testing unit an...
