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.
