چکیده
|
In this study, the polyethersulfone (pes) membranes were established by surface modification using c, n codoped-tio2/wo3 (ltw) photocatalytic nanocomposite to amelioration of the membrane performance in terms of antifouling and self-cleaning properties. the nanocomposite membranes were characterized by atr-ftir, sem, afm, and water contact angle (wca). the photocatalytic membranes’ performance was evaluated using assessment of the pure water flux (pwf), antifouling behavior, photoactivity, and long-term filtration. the membrane modification improved morphology and hydrophilicity of the membranes surface, contributing to the enhanced permeability (pwf of 49.65 kg/m2.h), and substantial antifouling property (frr of 96.96 %) as well as photoactivity (94.36 % dye removal) of the optimal photocatalytic membrane (m3 membrane). the long-term filtration of the optimal membrane represented its high performance and noteworthy antifouling resistance.
