“…Numerous studies have successfully combined antimicrobial GMs with polymeric membranes or foams to prevent biofouling ( Firouzjaei et al., 2020 ; Wang et al., 2019a ; Perreault et al., 2015a ). These composite materials can be employed for different applications such as ultrafiltration, nanofiltration, forward or reverse osmosis desalination, wastewater treatment, as well as radioactive metal recovery from seawater ( Zinadini et al., 2014 ; Choi et al., 2013 ; Lee et al., 2013 ; Perreault et al., 2014 ; Zeng et al., 2016 ; Guo et al., 2019 , 2020 ; Singh et al., 2018 ; Mokkapati et al., 2017 ; Bao et al., 2011 ). Recent studies describing GM-comprising membranes with antifouling capacity include the development of polysulfone coated with a PDA layer and GO nanosheets ( Cheng et al., 2020 ).…”

Summary Graphene materials (GMs) are being investigated for multiple microbiological applications because of their unique physicochemical characteristics including high electrical conductivity, large specific surface area, and robust mechanical strength. In the last decade, studies on the interaction of GMs with bacterial cells appear conflicting. On one side, GMs have been developed to promote the proliferation of electroactive bacteria on the surface of electrodes in bioelectrochemical systems or to accelerate interspecies electron transfer during anaerobic digestion. On the other side, GMs with antibacterial properties have been synthesized to prevent biofilm formation on membranes for water treatment, on medical equipment, and on tissue engineering scaffolds. In this review, we discuss the mechanisms and factors determining the positive or negative impact of GMs on bacteria. Furthermore, we examine the bacterial growth-promoting and antibacterial applications of GMs and debate their practicability.

“…Uranium is essential for the sustainable development of the nuclear industry, [1][2][3] the uranium content in the ocean (about 4.5 billion tons) is almost 1000 times that of uranium on land. 4,5 To achieve continuous development of nuclear energy and environmental protection, it is of considerable significance to develop effective technology for extracting uranium from natural seawater.…”

“…5,20 Recently, a few reports have synthesized antibacterial adsorbents with excellent performance by covalently cross-linking a broad-spectrum antibiotic into adsorbents 18 or doping silver ions on chitosan-graphene oxide foam substrate. 1 These methods can significantly improve the extraction ability of uranium from seawater. However, biotoxicity and leaching of precious metal nanoparticles may have a negative impact on the marine environment while sterilizing the adsorbent.…”

Biofouling is a major obstacle to the efficient extraction of uranium from seawater due to the numerous marine microorganisms in the ocean. Herein, we report a novel amidoxime (AO) crystalline covalent organic framework (BD-TN-AO) by Knoevenagel condensation reaction of 2,2′,2″-(benzene-1,3,5triyl)triacetonitrile (TN) and 4,4′-(buta-1,3-diyne-1,4-diyl)dibenzaldehyde (BD) that is highly conjugated and possesses excellent photocatalytic activity. The excellent photocatalytic activity endows the BD-TN-AO high anti-biofouling activity by producing biotoxic reactive oxygen species (ROS) and photogenerated electrons to efficiently reduce the loaded U(VI) to insoluble U(IV). Meanwhile, the surfacepositive electric field has strong electrostatic attraction to the negative [UO 2 (CO 3 ) 3 ] 4− in seawater, which can significantly enhance the extraction capacity of uranium. Benefiting from these outstanding photoinduced effects of BD-TN-AO, the adsorbent exhibits a high uranium adsorption capacity of 5.9 mg g −1 under simulated sunlight irradiation in microorganism-containing natural seawater, which is 1.48 times the adsorption capacity in darkness.

“…It is not surprising that LDHs have recently been combined with chitosan and GO to give efficient adsorbents with enhanced adsorption performances [ 215 , 216 ]. Recently, metal-organic frameworks (MOFs) have also been combined with CS/GO [ 217 , 218 ] to give good adsorption properties. MOFs have received considerable interest in environmental science and chemistry as these materials have high porosity and high specific surface areas, with tunable pore structures.…”

The quality of water is continuously under threat as increasing concentrations of pollutants escape into the aquatic environment. However, these issues can be alleviated by adsorbing pollutants onto adsorbents. Chitosan and its composites are attracting considerable interest as environmentally acceptable adsorbents and have the potential to remove many of these contaminants. In this review the development of chitosan-based adsorbents is described and discussed. Following a short introduction to the extraction of chitin from seafood wastes, followed by its conversion to chitosan, the properties of chitosan are described. Then, the emerging chitosan/carbon-based materials, including magnetic chitosan and chitosan combined with graphene oxide, carbon nanotubes, biochar, and activated carbon and also chitosan-silica composites are introduced. The applications of these materials in the removal of various heavy metal ions, including Cr(VI), Pb(II), Cd(II), Cu(II), and different cationic and anionic dyes, phenol and other organic molecules, such as antibiotics, are reviewed, compared and discussed. Adsorption isotherms and adsorption kinetics are then highlighted and followed by details on the mechanisms of adsorption and the role of the chitosan and the carbon or silica supports. Based on the reviewed papers, it is clear, that while some challenges remain, chitosan-based materials are emerging as promising adsorbents.
