“…In multiple works, the authors concluded that the iron oxide layer formed in situ during the heat treatment process enhanced the biofilm formation on the SS fiber felt surface, which greatly boosts the current production. , Despite their superior electrical response, the flame-oxidized SS fiber felts were not tested for their biosensing capabilities. To compensate SS material’s lack of biocompatibility, carbon-based catalysts were tested on SS electrodes as carbon-based materials possess excellent sensitivity . SS mesh modified with carbon black powder achieved a current density 3 times higher than unmodified SS mesh, which is in line with another work that demonstrated the superior performance of carbon powder-coated SS mesh as compared to pristine SS mesh and carbon felts .…”

Electrogenic microorganisms serve as important biocatalysts for microbial electrochemical sensors (MESes). The electrical signal produced is based on the rate of electron transfer between the microbes and electrodes, which represents the biotoxicity of water. However, existing MESes require complex and sophisticated fabrication methods. Here, several low-cost and rapid surface modification strategies (carbon powder-coated, flameoxidized, and acid-bleached) have been demonstrated and studied for biosensing purposes. Surface-modified MESe bioanodes were successfully applied to detect multiple model pollutants including sodium acetate, ethanol, thinner, and palm oil mill effluent under three different testing sequences, namely, pollutant incremental, pollutant dumping, and water dilution tests. The carbon powder-coated bioanode showed the most responsive signal profile for all the three tests, which is in line with the average roughness values (R a ) when tested with atomic force microscopy. The carbon powder-coated electrode possessed a R a value of 0.844, while flame-oxidized, acid-bleached, and control samples recorded 0.323, 0.336, and 0.264, respectively. The higher roughness was caused by the carbon coating and provided adhesive sites for microbial attachment and growth. The accuracy of MESe was also verified by correlating with chemical oxygen demand (COD) results. Similar to the sensitivity test, the carbon powder-coated bioanode obtained the highest R 2 value of 0.9754 when correlated with COD results, indicating a high potential of replacing conventional water quality analysis methods. The reported work is of great significance to showcase facile surface modification techniques for MESes, which are cost-effective and sustainable while retaining the biocompatibility toward the microbial community with carbon-based coatings.

“…Siloxane and graphene‐based imprinted polymers have been studied more for the removal of heavy metal ions and organic pollutants from water. It has also been shown that silicon‐based and graphene‐based imprinted polymers can have a significant impact in the drug delivery of 5‐FU [16–18] . In our study, ATP as a natural mineral, was used to prepare molecularly imprinted polymers by combining it with graphene after organosilylation and then polymerizing it with acrylamide and methyl methacrylate.…”

Molecularly imprinted polymers and non‐imprinted polymers based on attapulgite and graphene composite were synthesized by coating with copolymer of acrylamide and methyl methacrylate. The adsorption results showed that the molecularly imprinted polymers and non‐imprinted polymers could reach the maximum drug loading of 2.4 and 1.6 mg/g, respectively. The in vitro release studies demonstrated that molecularly imprinted polymers and non‐imprinted polymers can control the release of 5‐fluorouracil and reach maximum release at approximately 48 h. Cytotoxicity analysis showed that 100 μg/mL of molecularly imprinted polymers loaded with 5‐fluorouracil gradually increased the inhibition rate of HeLa with increasing time and approached the maximum inhibition rate of 20 % at 72 h.

“…Liquid-phase adsorption is thought to be the most efficient method of removing organic dyes from wastewater out of all of these different purification processes (Kamyab et al, 2022). For removing textile dyes from water, a variety of materials, such as chitosan (Shajahan et al, 2017), leaves (Chen et al, 2019), carob shells (Farnane et al, 2017), orange peels (Pandiarajan et al, 2018), coconut shells (Aljeboree et al, 2017), and Cucumis sativus peel (Shakoor & Nasar, 2017), were prepared or used as adsorbents.…”

In this study, the electrocoagulation (EC) treatment was used to minimize and separate pollutants from textile industrial wastewater (TIWW), including high color, chemical oxygen demand (COD), total organic carbon (TOC), and total dissolved solids (TDS). To enhance the EC treatment efficiency, a novel strategy has been followed in the study that involves thin‐film coating on 316 stainless steel (SS) electrodes with banana peel‐derived activated carbon (BPAC) by dip coating, spin coating, or spray coating. Among the different types of coating, thickness and contact angle measurements have elucidated that the spray coating of BPAC on SS electrode is the best tool with minimum thickness and contact angle. In this study, a bare SS electrode was used as the anode and a thin‐film spray‐coated BPAC on the SS electrode was used as the cathode. Moreover, optimization plays a key role in EC treatment process, where operating conditions such as a current density of 10 mA/cm2, contact time of 15 min, and a pH of 7 were fixed. As a result, the findings indicate comparatively high color removal of 98%, COD removal of 91%, TOC removal of 89.6%, and TDS removal of 68% are achieved with ease. Accordingly, in comparison with plain SS electrodes or dip‐ or spin‐coated BPAC on SS electrodes, spray‐coated BPAC on SS electrodes in EC treatment outperforms in removing high color, TOC, COD, and TDS. Overall, the study highlights the potential of EC treatment integrated with adsorption procedures for TIWW treatment. Particularly, the use of thin‐film spray‐coated BPAC on SS electrodes in the EC treatment process led to an effective and sustainable tool for treating and reuse of TIWW. It is due to its low operation and maintenance cost and studied in a short interval of time. Finally, the ultimate goal was firmly achieved in pilot‐scale studies by the safe discharge into the environment or reuse of treated textile wastewater. Thus, it is a promising alternative with an environmentally friendly footprint that could be easily implemented in any textile industry premises.Practitioner Points Heavy metals, oils, facts, suspended solids, and other pollutants can be removed from industrial effluent by using electrocoagulation. The process is both cost‐effective and energy‐efficient, and it is easily integrated with other water treatment technologies. According to the findings of this study, minimum current density should be applied to BPAC–SS‐coated electrodes by DC power supplies to treat textile industry effluents at low operating costs. When compared with a plain SS electrode, the spray‐coated BPAC on SS electrode provides better performance in effluent treatment.
