Fabrication and characterization of L-Asparagine monohydrate functionalized-TiO2/PES nanofiltration membrane with enhanced antifouling properties in removal of dye pollution from water

in this work, mixed matrix nanofiltration membrane was fabricated using PES and TiO2@L-Asparagine nanocomposite.The fabricated membrane showed higher water permeability and fouling resistance than the polyethersulfone (PES) membrane. For the mixed matrix membrane with 2.56wt% of TiO2@L-Asparagine nanocomposite, the water flux reached a maximum (16.32 Kg/m2h). Also, the fouling resistance of membranes by filtratuin of 1000ppm dry milk solution showed that the mixed matrix membrane with 2.56wt% of nanocomposite has the best anti-fouling property (Flux recovery rate, 93.05%). Finally, results of the performance of the membranes in the dye rejection of the reactive red 195 showed that the membrane with 2.56wt% of nanocomposite has the best dye rejection (96.92%) and water permeation rate in compared to other membranes.
