“…Hence, these membranes are classified as ultrafiltration (UF) membranes. Studies have shown that UF membranes incorporated with 2% of GO demonstrated highly efficient removal of organic dyes including MB molecules [24]. Besides, it can be observed that the porosity of the nanocomposite membrane showed an increasing trend.…”

It is reported that the membrane properties can be enhanced by nanomaterials. However, agglomeration will occur due to the overdose of nanomaterials subsequently deteriorating membrane performance. The project aims to investigate the effect of concentration of cabon nanomaterials: multiwalled carbon nanotubes (MWCNTs) and graphene oxide (GO), on nanocomposite membrane for methyl blue (MB) dye removal. The GO/MWCNTs nanocomposite membranes were synthesized using direct blending method with three concentrations (0.2, 0.5, and 1 wt.%). The synthesized membrane was characterized by surface hydrophilicity, pore size and porosity, surface charge, functional group, and surface morphology. Besides, the performance of the synthesized membrane was evaluated by water permeability test, dye rejection test, and antifouling test. The result shows that the surface hydrophilicity was enhanced when the concentration of nanomaterials increased up to 0.2 wt%. However, higher concentration of nanomaterials reduces the membrane hydrophilicity due to the agglomeration of nanomaterials. The membrane with nanomaterials concentration of 0.2 wt.% (M0.2) has the best performance as it showed 6.85% and 32% improvement in water permeability and dye rejection when compared to the pristine membrane. Besides, M0.2 membrane has relatively good antifouling properties indicated by normalized flux (0.8043). This is due to the enhancement of hydrophilicity and zeta potential of M0.2 membrane by carbon nanomaterials. In short, optimum concentration of carbon nanomaterials are essential to enhance the membrane performance as agglomeration of nanomaterials occurs at high concentration.

“…Generally, it is widely believed that the incorporation of GO into the membrane matrix can significantly enhance the membrane hydrophilicity and porosity, thus improving overall membrane performance and efficiency [16,17,33,34,35]. For example, promising results were reported by Rafal Sitko et al [34] on the effective adsorption of heavy metals ions (cobalt, nickel, copper, zinc, cadmium and lead) by GO/cellulose membranes.…”

“…Kadhim et al [31] reported the superior performance of PES membranes incorporated with GO for removal of acid black (AB) and rose bengal dyes (up to 99% rejection). Sunil et al [33] incorporated GO into PSf membrane in which the resulting membranes exhibited 100% removal of methyl orange, methyl blue, sulfon black F, Rhodamine 6G and malachite green dyes.…”

Adsorptive ultrafiltration membrane is an emerging field that holds great promise for achieving high efficiency removal of various pollutants such as metal ions and organic pollutants. As a result, significant research efforts have been directed towards the utilization of GO due to its unique properties including good hydrophilicity, large surface area, excellent chemical and mechanical stability which can impart better membrane properties and performance. Recent advances in this field revealed that the utilization of graphene oxide (GO) is highly beneficial in improving key membrane properties including surface charge, hydrophilicity, water permeability as well as the adsorption performance. Therefore, this short review provides valuable insight into the performance of GO/GO modified-based membranes, GO/polymeric-based membrane and GO-modified/polymeric-based membrane for various pollutants. The application of GO in ultrafiltration (UF) membranes is anticipated to provide an attractive and viable route towards achieving high performance adsorptive UF membranes for water and wastewater treatment.

“…Natural organic matter (NOM) such as humic acid (HA) and sodium alginate (SA) consist of hydrophobic aliphatic and aromatic moieties, allowing these types of foulants to be adsorbed on the membrane surface through hydrophobic interactions. Organic dyes (e.g., Congo red, methyl blue, rhodamine B, malachite green, methyl orange, rose Bengal dye, acid black 210, and so on [ 28 , 29 , 30 , 31 ]) are interesting foulants due to their complex structure, and electrical charge. In addition, dye effluents have high salinity due to the addition of salts (common practice by textile industries to enhance dye uptake) [ 28 , 32 ], which makes the fouling mechanism by organic dyes complex.…”

Recent Advances on the Fabrication of Antifouling Phase-Inversion Membranes by Physical Blending Modification Method

Membrane technology is an essential tool for water treatment and biomedical applications. Despite their extensive use in these fields, polymeric-based membranes still face several challenges, including instability, low mechanical strength, and propensity to fouling. The latter point has attracted the attention of numerous teams worldwide developing antifouling materials for membranes and interfaces. A convenient method to prepare antifouling membranes is via physical blending (or simply blending), which is a one-step method that consists of mixing the main matrix polymer and the antifouling material prior to casting and film formation by a phase inversion process. This review focuses on the recent development (past 10 years) of antifouling membranes via this method and uses different phase-inversion processes including liquid-induced phase separation, vapor induced phase separation, and thermally induced phase separation. Antifouling materials used in these recent studies including polymers, metals, ceramics, and carbon-based and porous nanomaterials are also surveyed. Furthermore, the assessment of antifouling properties and performances are extensively summarized. Finally, we conclude this review with a list of technical and scientific challenges that still need to be overcome to improve the functional properties and widen the range of applications of antifouling membranes prepared by blending modification.
