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...

PIM-1-based freestanding mixed matrix membranes (MMMs) and thin film nanocomposites (TFNs) were prepared by incorporating porous silica nanosheets (SN) exfoliated SN (E-SN) derived from natural vermiculite (Verm) in the PIM-1 polymer matrix. In addition, functionalized sulfonic acid amine groups (S-SN N-SN, respectively) also used as fillers for preparation of MMMs. The gas separation performan...

Advances in industrial ecology, desalination, and resource recovery have established that industrial wastewater, seawater, and brines are important and largely untapped sources of critical metals and elements. A Grand Challenge in metal recovery from industrial wastewater is to design and synthesize high capacity, recyclable and robust chelating ligands with tunable metal ion selectivity that c...

Cellulose and copolymers of acrylonitrile (PAN) are characterized by their chemical resistance to several conventional solvents. Therefore, these polymers often used obtain membranes for the recovery such In this work, first time, composite formed from highly concentrated mixed solutions based on cellulose PAN considered (the total content is 18 wt.%). For solutions, morphology rheological beha...

Over the past two decades, membrane processes have gained a lot of attention for the separation of gases. They have been found to be very suitable for wide scale applications owing to their reasonable cost, good selectivity and easily engineered modules. This critical review primarily focuses on the various aspects of membrane processes related to the separation of biogas, more in specific CO(2...

asymmetrically mixed matrix matrimid-mil-53 membranes with silicone cover layer were fabricated. for better understanding of membrane fabrication process, three main parameters of fabrication, matrimid concentration, silicone concentration and weight percentage of metal organic framework (mil-53) particles, were optimized by an experimental design method. cross-section sem images were used to s...

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...

Metal–organic frameworks (MOFs) are an emerging class of nanoporous materials comprising metal centers connected by various organic linkers to create one-, two-, and threedimensional porous structures with tunable pore volumes, surface areas, and chemical properties. Several thousand MOF materials have been synthesized and their numbers continue to grow rapidly. MOFs are predicted to be highly ...

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...
