Abstract In this work, a new model is developed by modifying the existing Maxwell–Wagner–Sillars (MWS) to predict gas separation properties of mixed matrix membranes (MMMs). The modified MWS model, for first time, provides simultaneous exploration role nanofillers/matrix interface voids and exact geometrical shape nanofillers in predicting MMMs. To unveil crucial voids, membrane considered thre...

In this study, novel mixed matrix membranes (MMMs) were synthesised by adding metal organic frameworks (MOFs) (UiO-66 and UiO-66-NH 2 ) to pristine sulfonated polyethersulfone (PES). The differing synthetic method resulting in MMM where additives grafted the polymer, or formed a natural interface, allowing impact of these features be investigated. composite characterised FTIR, PXRD, water conta...

Nanocomposite cation exchange membranes (CEMs) were prepared by adding various amounts of functionalized silica-coated magnetite nanoparticles to the sulfonated polyethersulfone (sPES) polymeric matrix. The particles were synthesized first by the co-precipitation method (M0). Different surface modifications were then carried out on them by grafting three functional groups of mercaptopropyl, pro...

Co-mixed cellulose acetate butyrate and permutit in a definite composition was prepared and coded as MRS-2.The membrane potential was measured with uni-uni valent electrolyte, NaCl solutions using saturated calomel electrodes (SCEs).The effective fixed charge density of the membrane was determined by TMS method and it showed dependence on the porosity, charge on the membrane matrix, charge and ...

In this work, polysulfone (PSf) mixed matrix membranes were prepared by incorporating modified montmorillonite with lysine amino acid (MMT-Lys) for arsenic removal from water. Different tests including XRD, zeta potential, FE-SEM, contact angle, and pure water flux (PWF) were carried out to characterize modified MMT and fabricated mixed matrix membranes. XRD analysis showed that MMT was success...

Biofouling impedes the performance of membrane bioreactors. In this study, we investigated the antifouling effects of polysulfone membranes that were modified by 1,2,3-triazole and palladium (Pd) nanoparticles. The modified membranes were evaluated for antibacterial and antifouling efficacy in a monoculture species biofilm (i.e., drip flow biofilm reactor, DFR) and mixed species biofilm experim...
