Abstract BACKGROUND The presence of pharmaceutical active substances such as diclofenac (DCF) and clofibric acid (CA) in aquatic environments poses significant ecological threats. Existing treatments have not fully explored the impact CA on DCF removal efficiency. This research introduces nZVI/CTAB‐SBE@C, a novel adsorbent developed from industrial spent bleaching earth (SBE), modified with cetyltrimethylammonium bromide (CTAB) nano zero‐valent iron (nZVI), enhancing both adsorption degradation CA. RESULTS study investigated capabilities nZVI/CTAB‐SBE@C for coexisting system. Systematic examinations were conducted effects various parameters, including reaction time, dosage, temperature, actual wastewater, humic content ions. Results indicated that significantly enhanced efficiency, achieving an optimal rate 87.3% under conditions time 2 h, dosage 5 g L −1 temperature 25 °C. Moreover, interactions between Al 3+ ions matrix notably improved efficiencies Analysis revealed facilitated new pathways DCF, hydroxylation decarboxylation reactions. Additionally, reduced toxicity intermediates, environmental safety compared to systems containing only DCF. CONCLUSION effectively transforms waste into efficient adsorbent. boosts efficiency but also promotes its safer degradation, thereby reducing contaminants. © 2024 Society Chemical Industry (SCI).

To examine the impact of antibiotic contamination on water quality and rhizospheric microbial communities, a simulated cultivation experiment was employed to investigate potential impacts tetracycline (Tet) stress community composition in rhizosphere Eichhornia crassipes (E. crassipes), with focus its implications for bioremediation strategies. The results showed significant disruption diversity structure at varying accumulated Tet concentrations (0, 2, 5, 10 mg·L−1). communities displayed resilience functional stability from low (2 mg·L−1) moderate (5 concentrations; while root decay marked decline were observed high (10 concentration. Some bacterial taxa, including Rhizobiaceae (0.34%), Comamonadaceae (0.37%), Chitinophagaceae (0.38%), exhibited notable enrichment under stress, underscoring their roles nitrogen cycling, organic matter decomposition, degradation. Physicochemical changes rhizosphere, such as shifts low-molecular-weight acids (LMWOAs), nutrient total carbon (TOC), revealed Tet-induced metabolic adaptations environmental alterations. Correlation analysis between factors dominant operational taxonomic units (OTUs) highlighted putative intricate interplay activity stress. These findings underscore dual both stressor selective agent, favoring antibiotic-resistant taxa suppressing sensitive groups. This study provides foundational insights into ecological dynamics conditions highlights Tet-polluted ecosystems.
