“…Safety concerns around the potential toxicity of specific nanomaterials necessitate thorough risk assessments and regulatory measures to ensure responsible use. Scalability challenges present another hurdle, requiring innovative engineering solutions to scale up nanotechnology applications for large-scale water treatment while maintaining cost-effectiveness (Livingston et al, 2020;Qu et al, 2013).…”
This research paper explores the adoption of nanotechnology in water treatment, focusing on the advanced perspective of the United States and the potential prospects across diverse landscapes in Africa. Investigating current trends, challenges, and ethical considerations, the USA is a model for cutting-edge research, robust regulatory frameworks, and innovative applications of nanotechnology. Meanwhile, Africa, grappling with water scarcity, presents an opportunity for leapfrogging with context-specific strategies and international collaboration. Environmental and ethical considerations are paramount, emphasizing the need for responsible practices, equitable distribution of benefits, and global justice. Future trends anticipate innovative nanomaterials, decentralized solutions, and green nanotechnology shaping water treatment practices. The conclusion underscores this journey's dynamic and collaborative nature, advocating for interdisciplinary efforts, international collaboration, and ethical governance to realize a sustainable future with nanotechnology as a critical catalyst for water security.

“…However, nanoparticles have a tendency to agglomerate [51,52], thus decreasing the beneficial effects of their size and reducing the active sites for reactions. Another problem related to the use of nZVI is the ultimate fate of those nanoparticles in the case of accidental release into the natural environment [53]. There is growing concern that nanomaterials may have serious toxic effects on several species of the aquatic and terrestrial biota.…”
Nano zerovalent iron (nZVI), produced from green tea extracts, was incorporated in a cation exchange resin (R-nFe) to investigate its performance regarding the removal of four non-steroidal anti-inflammatory drugs (NSAIDs): ibuprofen (IBU), naproxen (NPX), ketoprofen (KTP) and diclofenac (DCF). The effect of contact time, NaCl pretreatment, pH, R-nFe dose, the role of the supporting material, the initial concentration of pollutants, and the combined effect of nZVI with oxidative reagents was assessed through a series of batch experiments. According to the results, the best removal efficiencies obtained for DCF and KTP were 86% and 73%, respectively, at 48 h of contact time with NaCl pretreated R-nFe at a dose of 15 g L−1 and a pH of 4. The maximum removal efficiency for NPX was 90% for a contact time of 60 min with PS 1 mM and a pH of 3, which was quite similar to the experiment with a greater contact time of 48 h without PS addition. The maximum IBU removal was 70%; this was reached at pH 3, with a contact time of 30 min and R-nFe 15 g L−1. To the authors’ best knowledge, this is the first study investigating the utilization of nZVI, produced from leaf extracts and incorporated into a cationic exchange resin, to remove NSAIDs from water.
“…Thus, the RFX with the molecular formula (C 43 H 51 N 3 O 11 ), and chemical structure in Scheme 1 is as a widely used antibiotic for treating infectious diseases, a rapid, sensitive, and selective assay is necessary for its administration [ 4 ]. In recent years, material scientists have prioritised environmentally sustainable methods for synthesising nanoscale materials [ 5 ]. The synthesis of rifaximin nanoparticles, particularly using various rifaximin solutions, is an emerging field in environmentally friendly chemistry that is believed to be simple, cost-effective, and non-toxic [ 6 ].…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
