Silver, a valuable metal widely used in various industries, poses ecological and health risks when released into wastewater. Adsorption is an effective, cost-efficient method for silver removal, offering high efficiency and operational simplicity. Recent advancements have led to the development of advanced adsorbents with enhanced capacity and selectivity for silver ions. This review examines the mechanisms of silver adsorption, including electrostatic interactions, ion exchange, surface complexation, and redox reactions, and evaluates adsorbent performance through isotherms, kinetics, and thermodynamics. Key factors influencing adsorption, such as pH and competing ions, are analyzed, alongside emerging trends like sustainable adsorbents and hybrid technologies. Challenges, including adsorbent regeneration and scalability, are discussed, as are opportunities for resource recovery and circular economy approaches.

Modern physicochemical techniques to ecological restoration have grown in popularity in order to develop eco-friendly and long-term solutions. The goal of this research is to create a bio-nanomaterial capable of digesting organic pollutants and suppressing microbial infections while producing no undesirable by-products. <i>Veldt grape</i> (Vg) leaf extract was used to produce zinc oxide nanoparticles (ZnO NPs) utilizing a green technique. Multiple approaches were used to characterize the physicochemical properties of Vg-ZnO NPs. UV–vis spectroscopy confirmed a maximum absorption range of 360–368 nm, while XRD examination revealed a wurtzite hexagonal phase with crystallite sizes ranging between 6.6 and 13.1 nm. FTIR spectra indicated the presence of flavonoids, phenols, and hydroxyl groups, while SEM pictures revealed a petal-like morphology, which EDAX validated for elemental composition. The photocatalytic activity of Vg-ZnO NPs was tested for MB dye degradation, and they achieved 90.6% disintegration during 120 min of UV light irradiation, with catalyst dose, dye concentration, pH, and reusability optimized. Antimicrobial effectiveness was evaluated against <i>Edwardsiella tarda, Klebsiella pneumoniae, Staphylococcus aureus, and Candida albicans,</i> with <i>K. pneumoniae</i> having the largest inhibition zone of 25 mm. The improved photocatalytic and antibacterial properties of Vg-ZnO NPs highlight their potential for organic pollutant breakdown and environmental remediation.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":513,"journal":{"name":"Chemical Papers","volume":"79 9","pages":"5747 - 5763"},"PeriodicalIF":2.5,"publicationDate":"2025-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144918260","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The preparation and characterization of nanosilica from shakhotaka and bamboo leaf biomass waste were the main objectives of this investigation. Shakhotaka (X = K) and bamboo (X = B) leaf biomass waste were converted into nanosilica using three acid (1 M HCl) pretreatment techniques: refluxing for 1 h (X-Rf-800), stirring for 12 h (X-H12-800), and stirring for 24 h (X-H24-800) before thermal combustion at 800 °C for 5 h under an air atmosphere.
