The shortage of clean water sources and increase of demand for fresh water have become as major globalchallenges not only in industries but also inhuman life. Meanwhile, membrane technology has beenextensively noticed due to high separation efficiency, energy-saving and environmentally-friendly characteristic. So, development of new membrane is a vital step in advancing of membrane application inwater-treatment. This paper presents a comprehensive review on development of high-performancenanofiltration membrane based on nanotechnology for wastewater treatment. Application of new nanomaterialshas enabled fabrication of NF-membranes with improved separation properties for pollutantsremoval from water. Recognizing that conventional membranes are not necessarily suitable for industrialapplications and/or process intensifications many attempts were made recently to use of nanomaterialsinto NF-membranes, aiming to overcome trade-off relationship between flux/selectivity and to improvetheir stability. So, development of new structured nanomaterial with desirable properties is one of mostcrucial research topics for membrane researchers. Accordingly, an overview on different methods todesign of advanced nanomaterial presented that allow us to overcome their inherent problems in membranesfabrication such as agglomeration, defects formation, insufficient pores’ tuning, poor active sitesand anti-fouling properties; however, selection of appropriate nanomaterials is a challenge of utmost difficulty. Various types of nanomaterials such as zeolites, carbon based, framework (MOF/ZIF/COF), nanobiopolymersand special nanoparticles such as SFNPs, SFNCs, POSS, ZCPs, and nickel hydroxide nanosheetare presented and their roles in NF-transport are discussed as well as strategies for surface modificationof nanoparticles to promoting their surface charges density. Moreover, fabrication methods of nanoenhanced NF-membranes including layer by layer assembly, hollow fiber spinning, electrospinning ofnanofibers, construction of thin-film nanocomposite besides blending, co-polymerization; cross-linkingand grafting techniques are discussed. A proper view for selection of appropriate nanoparticles in membranefabrication is offered while considering types of pollutants to be removed.

L-cysteine as an amino acid was used for the modification of glycidyl POSS in the synthesis of L-cysteine functionalized POSS, including carboxyl, hydroxyl, and diamine groups. Then, the synthesized nanoparticles were applied to fabrication of L-cysteine POSS-TiO2 composite nanoparticles. NF membranes were prepared from the incorporation of different concentrations of the synthesized composite nanoparticles into the polyether-imide (PEI) as the membrane matrix. The prepared membranes were characterized by Fourier transform infrared spectroscopy (FTIR), Field emission scanning electron microscopy (FESEM) and atomic force microscope (AFM). Moreover, the separation performance of the NF membranes was examined by pure water flux (PWF) and the separation of Na2SO4, Pb(NO3)2, Cr(NO3)2 and Cu(NO3)2 aqueous solutions. The results showed the increase of pure water flux due to present hydrophilic groups on the membrane surface. The highest pure water flux obtained was 22.03 L/m2 h in 1 wt% of nanoparticles. Furthermore, the rejection of Na2SO4 and Pb(NO3)2, CrSO4, and Cu(NO3)2 improved to 78%, 64%, 67% and 66% that increased 11%, 33%, and 22%, and 39% compared with the pristine PEI membrane, respectively. Finally, the best FRR% (81%) was obtained for 0.1 wt% of the composite nanoparticles (M3).

A new type of polyether-imide (PEI)-based nanofiltration membranes was prepared by introducing octaglycidyloxypropyl- silsesquioxane (Glycidyl POSS) into PEI matrix for heavy metals ions removal from water. The separation performance of fabricated membranes in Na2SO4, Pb(NO3)2, Ni(NO3)2 and Cu(NO3)2 removal from water as well as their flux and antifouling property was evaluated. Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM), energy dispersive X-ray (EDX) analytical method, atomic force microscope (AFM), porosity, contact angle, and water content were also used in membrane characterization. The results indicated higher hydrophilicity, pure water flux (PWF) and salt rejection for PEI-POSS membranes compared to neat PEI ones. The morphological images showed good tuning porosity, finger- and spongy-like structure. The highest porosity observed for [PEI-1 wt% glycidyl POSS] with the best antifouling property. The surface roughness also decreased by incorporating of POSS into PEI matrix. The pure water flux increased from 14.3 (L/m2h) for neat PEI membrane to 36 (L/m2h) for [PEI-0.1 wt% glycidyl POSS]. Moreover, Na2SO4, Pb(NO3)2, Cu(NO3)2 and Ni(NO3)2 rejection measured 78%, 94%, 99%, 42% for [PEI-1 wt% glycidyl POSS] membrane, whereas they were 69%, 44%, 40% and 16% for the virgin PEI membrane, respectively. Results showed a good potential for [PEI-POSS] membrane in Cu and Pb ions removal beside its high PWF and antifouling ability.

Surface functionalization of zinc oxide (ZnO) nanoparticles was performed by glycidyl POSS. The synthesized nanoparticles were applied to prepare polyether-imide based-nanofiltration membranes by phase inversion method. The characterizations were done by FESEM, EDX and AFM analysis. The effect of different concentrations of POSS-ZnO (PZ) nanoparticles was investigated to evaluate the separation performance of prepared membranes by contact angle measurement, pure water flux (PWF), rejection of aqueous solutions including Na2SO4, Pb(NO3)2, Cu(NO3)2 and flux recovery ratio (FRR%). The prepared PEI/PZ membranes showed significant separation performance and antifouling properties compared with neat PEI and PEI/ZnO membranes. The highest pure water flux (42.4 L/m2h) was revealed for M1-PZ in 0.001 wt% of PZ nanoparticles, whereas that was 17 (L/m2h) for neat membrane and 12-18 (L/m2h) for PEI/ZnO, respectively. Also, salt rejection was low for blended PEI/ZnO membranes. By incorporation of PZ into the PEI, Na2SO4, and Pb (NO3)2 rejection improved to 83% and 59%, respectively. Moreover, the M3-PZ showed the best separation performance for Cu (NO3)2 with the rejection of 67%. The highest antifouling properties were obtained for M4-PZ with FRR% of 59%, which is significant compared with 15% for PEI/ZnO and 30% for neat PEI membranes.

Sayed Mohsen Hosseini,Alireza Hamidi,Abdolreza Moghadassi,Fahime Parvizian,Sayed Siavash Madaeni 한국화학공학회 2015 Korean Journal of Chemical Engineering Vol.32 No.9

Polyvinyl chloride based/FeTiO3-co-Fe3O4 nanoparticles mixed matrix heterogeneous cation exchange membranes were prepared by solution casting technique. The effect of using filler additives in casting solution and also electrolyte concentration and pH on electrochemical properties of membrane was studied. Membrane potential, transport number and selectivity were improved by using FeTiO3/Fe3O4 nanoparticles in membrane matrix. Utilizing FeTiO3/ Fe3O4 nanoparticles in membrane matrix also led to improvement of membrane ionic flux from 2.95*10−5 to 4.15*10−5 (mol/m2·s) obviously. Similar trend was also found for membrane electrical conductivity. Moreover, the transport number, selectivity and membrane electrical conductivity were enhanced by increase of electrolyte concentration. Prepared membranes exhibited higher transport number/selectivity at pH 7 compared to other pH values. Obtained results showed that the membrane electrical resistance decreased initially by increase of electrolyte pH sharply and then began to increase. Membranes exhibited lower selectivity for bivalent ions compared to monovalent type. Modified membranes containing FeTiO3/Fe3O4 nanoparticles showed more appropriate electrochemical properties compared to other prepared membranes.

Mixed matrix polyethersulfone (PES) based nanofiltration membrane was prepared through phase inversion method by using of polyvinylpyrrolidone (PVP) as pore former and N, N dimethylacetamide (DMAc) as solvent. Polyaniline-co-graphene oxide nanoplates (PANI/GO) were utilized as additive in membrane fabrication. The PANI/ GO nanoplates were prepared by polymerization of aniline in the presence of graphene oxide nanoplates. FTIR analysis, scanning electron microscopy (SEM), scanning optical microscopy (SOM), 3D images surface analysis, water contact angle, water content tests, tensile strength tests, porosity tests, salt rejection and flux tests were used in membrane characterization. FT-IR results verified formation of PANI on graphene oxide nanoplates. SOM images showed uniform particles distribution for the mixed matrix membranes. SEM images also showed formation of wide pores for the modified membranes. Water flux showed constant trend nearly by use of PANI/GO in the casting solution. Opposite trend was found for the membrane surface hydrophilicity. Salt rejection was enhanced sharply by utilizing of PANI/ GO. The membrane’s tensile strength was improved by increase of PANI/GO concentration. The water content was increased initially by use of PANI/GO nanoplates up to 0.05%wt into the casting solution and then decreased. Membrane porosity was also enhanced by using of PANI/GO nanoplates. Modified membrane containing 0.5%wt PANI/ GO nanoplates showed more appropriate antifouling characteristic compared to others.
