Abstract
In this current work, a proper membrane was fabricated via vapor induced phase separation (VIPS) coupled with the non-solvent induced phase separation (NIPS). First, synthesized hydrogen peroxide treated exfoliated graphitic carbon nitride (H2O2-g-eC3N4) nanosheets were incorporated into the mixed matrix membrane (MMM). Then, synthesized NH2-MIL-101(Al) nanoparticles were incorporated into the MMM. In the next step, the synergistic effect of NH2-MIL-101(Al) and H2O2-g-eC3N4 was investigated systematically, and the optimized proportion of each modifier was acquired. The optimized membrane elucidated a high flux rate that reached as high as 20.7 ± 1.01 L m−2 h−1.bar−1, which was almost 62% higher than pristine PVDF membrane. It came across that the optimum membrane could provide a high dye rejection properties (99.9%, 99.8%, 99.7%, 99.3%) for orange G (OG), sunset yellow FCF (SY), naphthol yellow S (NYS), and Martius yellow (MY), respectively. Significant antifouling feature (96% for the optimum membrane), and outstanding long-term stability. Moreover, it was found that the synergistic effect of used dual nanoparticle/nanosheet caused promising long rejection stability even after 12 days.
