Item Effective removal of hazardous atrazine and chlorpyrifos by waste PET bottles-derived linker having novel MIL-53(Al)/PMMA-nanofiber incorporated poly(vinylidene) fluoride membranes(Elsevier Ltd, 2025) Prabhakar, N.; Isloor, A.M.; Farnood, R.Synthesis of novel MIL-53(Al)/PMMA nanofiber and its incorporation into PVDF thin-film composite flat-sheet membranes for the rejection of hazardous herbicides and pesticides from water is the crux of this work. Initially, poly (methyl methacrylate) polymer dope solution with MIL-53(Al) dispersed in the matrix was subjected to electrospinning to get a novel nanofiber. The linker terephthalic acid, here was derived from waste PET bottles. Both the MOF and nanofibers were characterized using BET, FTIR, zeta potential, and XRD. The optimized nanofibers were used as additives in the TFC in different weight percentages using synthesized porous PVDF as support. TFC Membranes were analyzed by pure water flux, chlorpyrifos, and atrazine rejection. MPM-2 with 0.05 wt% nanofiber gave a pure water flux of 18.6824 Lm?2h?1. The rejection of chlorpyrifos (a hazardous pesticide) was 86.8 % for MPM-2 membranes and atrazine (a herbicide) gave rejection of 60.48 %. Further, membranes gave excellent antifouling property with FRR of 95.45 %. © 2025 Elsevier LtdItem High performance 2D molybdenum MXene polyphenylsulfone membranes for boosting water flux and efficient removal of humic acid, antibiotic and dyes from wastewater(Elsevier B.V., 2025) Satishkumar, P.; Isloor, A.M.; Farnood, R.MXene, a leading two-dimensional material, is attracting scientists due to its rich polar surface termination and compatibility. Through the etching of an aluminum layer from Mo3AlC2, we have effectively produced molybdenum MXene Mo3C2Tx (where T stands for polar moieties like –OH and ?F) and used it to fabricate a new Mo3C2Tx embedded mixed matrix membrane. By the incorporation of highly hydrophilic Mo3C2Tx MXene into polyphenylsulfone (PPSU) membrane, its water flux tremendously increased to a peak value of 290 L m-2h?1 and is higher than 300 % compared to pristine polyphenylsulfone membrane without Mo3C2Tx MXene. Water contact angle study of Mo3C2Tx MXene embedded membranes showed improvement in hydrophilicity with an increase in its loading. Mo3C2Tx-PPSU membrane demonstrated appreciable antifouling nature and pollutant separation efficacy. The optimal membrane revealed 98.68 %, 96.7 %, 84.72 %, and 80.2 % removal of toxic contaminants like humic acid, RB 5 dye, RO 16 dye, and tetracycline antibiotic, respectively. This study offers a novel Mo3C2Tx embedded polyphenylsulfone membrane for wastewater treatment that eliminates potentially harmful humic acid, antibiotics, and dyes. © 2025Item Fabrication and incorporation of MIL-53(Fe)-zwitterionic brushes into PVDF thin film composite membranes for enhancing heavy metal/dye rejection from aqueous body(Elsevier B.V., 2025) Prabhakar, N.; Isloor, A.M.; Farnood, R.; Fauzi Ismail, A.The bioaccumulation of heavy metal ions is a serious concern for researchers. The dyes and heavy metal ions also aquatic life impacting the biodiversity adversely. Synthesis of novel MIL-53(Fe)-PSBMA particles, and its incorporation into PVDF-based thin-film composite membranes is the crux of this work. Firstly, H2N-MIL-53(Fe) was synthesized by metal displacement reaction which was then modified into MIL-53(Fe)-PSBMA brushes. The brushes were synthesized by atom transfer radical polymerization method. The amine groups of the NH2-MIL-53(Fe) help connecting the MOF to the polymeric moiety. The as-synthesized material and the fabricated TFCs were characterized by BET, FTIR, XRD, XPS, TGA, AFM, FE-SEM, zeta potential, and DLS particle sizer. The presence of sulphur groups on the XPS spectrum of modified MOF ensured the successful polymer grafting on it. Zwitterionic moieties have both positive and negative charges within a single molecule which gave a resultant zeta potential of ?13.1 mV for the brushes. A pure water flux of 26.32 Lm?2 h?1 and 97.33 %, 95.19 %, 82.06 %, and 78.47 % rejections for Pb2+, Hg2+, As3+, Cd2+ ions and 96.23 % and 94.04 % rejection for 100 ppm reactive black-5 and sunset yellow dyes respectively were obtained for the optimized membrane having 0.035 wt% loading of zwitterionic MOF. This result was attributed to the enhanced membrane hydrophilicity which was also correlated with contact angle and water uptake studies. © 2024 Elsevier B.V.
