“…The pore size of CPT membrane is higher than that of CPC membrane. However, from the pore size both of them are microfiltration membrane because the pore size is in the range 100 nm -10.000 nm [17].…”

Abstract. In this study, cellulose acetate/polyethylene glycol (CA/PEG) membrane with composition 80/20 was prepared by phase inversion method. Titanium dioxide with different number has been added by using surface coating. Hydrophilicity, morphology, flux permeate and salt rejection of membranes has been studied. The hydrophilicity is determined by FourierTransformed Infra-Red (FTIR) spectra and contact angle analysis. Surface and fractured morphology are identified by using Scanning Electron Microscopy (SEM). The experiment results show that hydrophilicity of CA/PEG membrane increases with the addition and the increasing of TiO2 contents. However, with further increasing of TiO2, hydrophilicity of CPT membrane decreases. The optimum membrane is CA/PEG/TiO2 80/20/1,25 g/L solvent (CPT 3) with flux permeate of 111,82 L.m-2h-1 and salt rejection of 48,30%.

“…It can be applied as a white pigment for paints, cosmetics and foodstuffs or an additive to functional construction materials for air and water purification, self-cleaning or antimicrobial protection [14], and its photocatalytic activity was shown in many studies [15]. In addition, there were also several research works focusing on supplementing of TiO 2 on the electrospun membrane [15], although their application were aimed mainly on their filtration properties than the photocatalytic ones [16].…”

Abstract:Recently electrospinning has gained significant attention due to unique possibilities to produce novel natural nanofibers and fabrics with controllable pore structure. The present study focuses on the fabrication of electrospun fibres based on gum karaya (GK), a natural tree gum, with polyvinyl alcohol (PVA), and functionalization of the membrane with TiO2 nanoparticles with further methane plasma treatment. The GK/PVA/TiO2 membrane was analyzed with several techniques including: fourier-transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDX), and water contact angle, in order to characterize its morphological and physicochemical properties. The GK/PVA/TiO2 membrane was further successfully used for the degradation (under UV irradiation) of bisphenol A and diclofenac from aqueous solution. It was also observed that the degradation kinetics of these compounds are faster in comparison to the UV treatment alone.

“…It is believed that incorporation of nanomaterials would play an important role in improving membrane properties such as hydrophilicity, selectivity and water permeability [4][5]. In recent years many nanoparticles have been utilized in fabrication of TFN membranes, including zeolites [7,8,9] TiO2 [10], Ag, CNTs and silica [5]. Furthermore, incorporation of nanomaterials into thin film structures has significantly improved the performances of available composite nanofiltration membrane and reverse osmosis membranes.…”

Abstract. Thin film nanocomposite (TFN) membrane with copperaluminium layered double hydroxides (LDH) incorporated into polyamide (PA) selective layer has been prepared for magnesium sulphate salt removal. 0, 0.05, 0.1, 0.15, 0.2 wt% of LDH were dispersed in the trimesoyl chloride (TMC) in n-hexane as organic solution and embedded into PA layer during interfacial polymerization with piperazine. The fabricated membranes were further characterized to evaluate its morphological structure and membrane surface hydrophilicity. The TFN membranes performance were evaluated with divalent salt magnesium sulphate (MgSO4) removal and compared with thin film composite (TFC). The morphological structures of TFN membranes were altered and the surface hydrophilicity were enhanced with addition of LDH. Incorporation of LDH has improved the permeate water flux by 82.5% compared to that of TFC membrane with satisfactory rejection of MgSO4. This study has experimentally validated the potential of LDH to improve the divalent salt separation performance for TFN membranes.
