This work explored the combined antibacterial and selective dye adsorption properties of graphene oxide (GO) incorporated into nanostructured polyethersulfone (PES) membranes. For this purpose, GO synthesis was performed by the Hummers method and characterized by Fourier transform infrared, X‐ray diffraction, Raman spectroscopy, and scanning electron microscopy (SEM) micrographs, using a graphite source as a reference. The dye adsorption capacity of GO was evaluated, obtaining a retention of ca. 66% with methylene blue (MB) and ca. 72% with methyl orange, higher than activated charcoal. In addition, the antibacterial properties of GO were evaluated against Staphylococcus aureus and Pseudomonas aeruginosa, with complete bacterial inhibition after 2 h of contact. GO was successfully incorporated into electrospun PES fibers to fabricate hybrid PES membranes, with a PES film (phase inversion) as substrate and an electrospun surface coating with PES/GO (at 1 wt%) fibers, corroborated by SEM micrographs. As a result, the hybrid PES membrane demonstrates an AA ca. 85% after 2 h of contact with both microorganisms and an improvement in colorant retention after two and four cycles of filtration, respectively. In addition, the adsorption isotherm and kinetics demonstrate the enhancement of the PES/GO membrane's performance in contact with MB solutions. Our results suggest that the GO incorporation into nanostructured hybrid membranes improves the fabrication of multifunctional NF membranes, with a potential application in wastewater treatment. Highlights Combined antibacterial/dye adsorption capacity of PES/GO membranes was found. Nanostructured membrane by PES and PES/GO fibers decorated was obtained. PES/GO demonstrates antibacterial features against Staphylococcus aureus and Pseudomonas aeruginosa. Enhanced dye adsorption capacity of PES/GO membrane was performed with MB. PES/GO membranes show properties for successful NF membrane development.

“…Among the biological processes, it is possible to enumerate the following as examples: activated sludge [ 130 ], microalgae treatment [ 131 ], biofiltration [ 132 ], and constructed wetlands [ 133 ]. Photoreaction can also be used to eliminate some pharmaceuticals, as reviewed by Abd Rahman, Choong [ 134 ], as well as filtration/adsorption processes [ 135 , 136 ] and advanced oxidation processes [ 137 ]. In this review, these strategies will not be discussed in detail since it is possible to find a vast number of recent review articles describing different strategies to remove pharmaceuticals and ECs in general [ 131 , 132 , 133 , 134 , 135 , 136 , 137 ].…”

Pharmaceuticals are present as pollutants in several ecosystems worldwide. Despite the reduced concentrations at which they are detected, their negative impact on natural biota constitutes a global concern. The consequences of pharmaceuticals’ presence in water sources and food have been evaluated with a higher detail for human health. However, although most of the pharmaceuticals detected in the environment had not been designed to act against microorganisms, it is of utmost importance to understand their impact on the environmental native microbiota. Microbial communities can suffer serious consequences from the presence of pharmaceuticals as pollutants in the environment, which may directly impact public health and ecosystem equilibrium. Among this class of pollutants, the ones that have been studied in more detail are antibiotics. This work aims to provide an overview of the impacts of different pharmaceuticals on environmental biofilms, more specifically in biofilms from aquatic ecosystems and engineered water systems. The alterations caused in the biofilm function and characteristics, as well as bacteria antimicrobial tolerance and consequently the associated risks for public health, are also reviewed. Despite the information already available on this topic, the need for additional data urges the assessment of emerging pollutants on microbial communities and the potential public health impacts.

Humankind has grown ever more dependent on mineral fertilizer to feed a growing world population. However, nutrients are rarely recovered and recycled after consumption, leading to environmental waste issues now and potential supply issues in the future. Urine is rich in these nutrients and therefore a prime candidate as precursor for biobased fertilizers. This work presents a case study to remove contaminants – predominantly pharmaceuticals – from human urine using activated carbon adsorbents in an effort to adhere to Dutch fertilizer legislation. In the urine, three pharmaceuticals were identified by target analysis and 11 other contaminants by suspect screening using liquid chromatography quadrupole time of flight mass spectrometry (LC-QTOF/MS). These were successfully removed by treatments with both granulated and powdered activated carbon, albeit with a loss of 16-17% and 2-4% of dissolved nutrients, respectively. Further screening of inorganic contaminants and persistent organic pollutants by inductively coupled plasma mass spectrometry (ICP-MS) and gas chromatography quadrupole-orbitrap mass spectrometry (GC-Q-Orbitrap/MS) showed that all prerequisites for fertilizer status are met, paving the way for its future legal use as biobased fertilizer in the Netherlands.
