“…[ 42 ] However, MOF‐based MMMs have mainly focused on industrially relevant gas separation applications, [ 43–49 ] and their application for water remediation has been barely explored. [ 50–52 ] This includes removal of organic dyes, [ 53 ] arsenate, [ 54 ] humic acid, [ 55 ] for antifouling properties, [ 56 ] or simply to increase flux while rejecting impurities. [ 57 ] To the best of our knowledge, no MOF‐based MMMs have been reported for the removal of mercury species from water.…”

The mercury removal efficiency of a novel metal‐organic framework (MOF) derived from the amino acid S‐methyl‐L‐cysteine is presented and the process is characterized by single‐crystal X‐ray crystallography. A feasibility study is further presented on the performance of this MOF—and also that of another MOF derived from the amino acid L‐methionine—when used as the sorbent in mixed matrix membranes (MMMs). These MOF‐based MMMs exhibit high efficiency and selectivity—in both static and dynamic regimes—in the removal of Hg2+ from aqueous environments, due to the high density of thioalkyl groups decorating MOF channels. Both MMMs are capable to reduce different concentration of the pollutant to acceptable limits for drinking water (<2 parts per billion). In addition, a novel device, consisting of the recirculation and adsorption of contaminated solutions through the MOF–MMMs, is designed and successfully explored in the selective capture of Hg2+. Thus, filtration of Hg2+ solutions with multiple passes through the permeation cell shows a gradual decrease of the pollutant concentration. These results suggest that MOF‐based MMMs can be implemented in water remediation, helping to reduce either contaminants from accidental unauthorized or deliberate metal industrial dumping and to ensure access for clean and potable freshwater.

“…Dye molecules typically exist in complex forms (after binding with other molecules). They are generally resistant to aerobic digestion, light, heat, or oxidants, making them difficult to treat using the conventional wastewater treatment process [ 52 , 53 ]. Because of their complex structures and the presence of benzene rings (aromatic), they are difficult to biodegrade, and thus it is essential to physically remove them.…”

“…A common approach to increase the dye rejection of membranes is to incorporate adsorbent filler materials into the membrane matrix ( Table 2 ). For example, it was reported that the incorporation of adsorbent filler materials (e.g., GO [ 55 ], MIL-125 [ 54 ], MOF-2(Cd) [ 53 ], and SnO 2 [ 56 ]) into the porous membrane matrices led to dye rejection improvements. For GO, it is postulated that its conjugated two-dimensional structure [ 55 ] encourages π-π stacking interactions with the dyes, thereby stimulating the adsorption of dye molecules onto the MMM.…”

“…The optimization of membrane surface charge or pore size is another facile way to increase the dye rejection of porous membranes. For example, the incorporation of filler materials to render the membrane surface more negatively charged has shown success in increasing dye rejection (for negatively charged dyes such as acid black) because of electrostatic repulsion effects [ 46 , 53 , 55 ]. Secondly, dyes can be rejected via the size exclusion effect when the size of the hydrated dye ions exceeds the pore size of the membrane ( Figure 4 D).…”

Emerging Materials to Prepare Mixed Matrix Membranes for Pollutant Removal in Water

et al. 2021

Various pollutants of different sizes are directly (e.g., water-borne diseases) and indirectly (e.g., accumulation via trophic transfer) threatening our water health and safety. To cope with this matter, multifaceted approaches are required for advanced wastewater treatment more efficiently. Wastewater treatment using mixed matrix membranes (MMMs) could provide an excellent alternative since it could play two roles in pollutant removal by covering adsorption and size exclusion of water contaminants simultaneously. This paper provides an overview of the research progresses and trends on the emerging materials used to prepare MMMs for pollutant removal from water in the recent five years. The transition of the research trend was investigated, and the most preferred materials to prepare MMMs were weighed up based on the research trend. Various application examples where each emerging material was used have been introduced along with specific mechanisms underlying how the better performance was realized. Lastly, the perspective section addresses how to further improve the removal efficiency of pollutants in an aqueous phase, where we could find a niche to spot new materials to develop environmentally friendly MMMs, and where we could further apply MMMs.

Preparation of High Stability Graphene Oxide/Zinc Oxide Composite Membrane via Vacuum Filtration for Separation of Methylene Blue from Aqueous Solution

In the present work, an excellent stable low graphene oxide/zinc oxide (LGO‐ZnO) composite membrane based on LGO nanosheets and ZnO nanonods has been successfully synthesized by vacuum filtration. The resultant graphene oxide nanosheet with a low degree of oxidation (LGO) was successfully prepared with the C/O ratio of 4.8 after stripped and oxidized. Importantly, the characterization results also demonstrated that ZnO nanorods were successfully intercalated into adjacent LGO nanosheets, rendering enlarged mass transfer channels, elevating hydration capacity and creating hierarchical nanostructures of membrane surfaces. Meanwhile, the stability of LGO‐ZnO composite membrane was enhanced obviously due to intercalation of ZnO nanorods, which was much more stable than that of LGO in aqueous solution. And it also exhibited outstanding permeation and separation performance for the water and various dyes solution system (with different concentration, volume or dye species), respectively. Accordingly, the permeate fluxes exhibited a drastic increase from 73 L/m2/h for LGO membrane to 1313 L/m2/h for LGO‐ZnO membrane. All the above results suggested that LGO‐ZnO membrane with high stability, high water permeability and favorable separation efficiency could be used as the great prospects membrane materials in separation of dyes from aqueous solution.
