This study focuses on the development of flat sheet thin film nanocomposite (TFN) pressure retarded osmosis (PRO) membranes for enhancement osmotic power generation by incorporation laboratory-synthesised graphene oxide (GO) into polysulfone (PSf) polymer matrix. A series containing different weight percent GO (0, 0.1, 0.25, 0.5 and 1.0 wt%) were fabricated via a phase inversion method with polyethylene glycol (PEG) as pore forming agent. The results show that TFN-0.25GO membrane has...
The interaction of As(V) with zerovalent iron (ZVI) and H2O system was studied under oxic anoxic conditions. XRD XPS analysis the ZVI confirmed core–shell Fe0 structure an outer coating oxide/hydroxide. Batch experiments showed that rate removal very fast for compared to condition. Under open atmospheric environment, revealed spontaneously reacts water oxygen form a number oxide/hydroxides is removed from solution by sorption/coprecipitation onto these corrosion products. However, reduction...
The non-selective property of conventional polyurethane (PU) foam tends to lower its oil absorption efficiency. To address this issue, we modified the surface properties PU using a rapid solvent-free functionalization approach based on chemical vapor deposition (CVD) method establish an extremely thin yet uniform coating layer improve performance. was respectively functionalized different monomers, i.e., perfluorodecyl acrylate (PFDA), 2,2,3,4,4,4-hexafluorobutyl (HFBA), and...
An artificial polydimethylsiloxane/polyphenylsulfone (PDMS/PPSU) membrane, which emulates the hydrophobic behavior of natural membranes, was synthesized. Hydrophobicity achieved by coating membrane surface sublayer using conventional silicon material, imitates character epicuticular wax (EW) Prunus laurocerasus L. leaves. It then applied as a separation medium in pervaporation (PV) diluted mixtures ethyl acetate and aroma compounds. The membrane's biomimetic characteristics were evaluated...

Glycerin and silica nanoparticles added into the polymer solution to investigate their effects on material properties gas separation performance of prepared membranes. The morphology structure PPSU analyzed scanning electron microscopy (SEM), surface roughness selective layer was atomic force (AFM), free energy calculated based contact angle measurements using various solvents....
An investigation of the effect molecular weight polyethylene glycol (PEG) on thin-film composite (TFC) flat sheet polysulfone membrane performance was conducted systematically, for application in forward osmosis (FO) and pressure retarded (PRO). The TFC PSf-modified membranes were prepared via a non-solvent phase-separation technique by introducing PEGs different weights into dope solution. PSf-PEG characterized SEM, FTIR AFM. PSf modified with PEG 600 found to have optimum composition....
Pressure-retarded osmosis (PRO) has recently received attention because of its ability to generate power via an osmotic pressure gradient between two solutions with different salinities: high- and low-salinity water sources. In this study, PRO performance, using the pilot-scale membrane modules configurations—five-inch cellulose triacetate hollow-fiber module (CTA-HF) eight-inch polyamide spiral-wound (PA-SW)—was evaluated by changing draw solution (DS) concentration, applied hydrostatic...
Incorporation liquid into membrane polymer pores structure would overcome challenges in developing a with increasing gas permeability while maintaining the excellent selectivity. Asymmetric Polyvinylidene fluoride-co-polytetrafluoroethylene (PVDF-co-PTFE) and PVDF-co-PTFE/Deep Eutectic Solvent (PVDF-co-PTFE/DES) supported was prepared using phase inversion method. Membranes were coated 3 wt. % of polydimethylsiloxane (PDMS) n-hexane dried room temperature. While, deep eutectic solvent (DES)...
