In this study, seventeen antibiotics and metabolites of five therapeutic groups of critically and highly important antibiotics were monitored in wastewater and sludges from fifteen wastewater treatment plants (WWTPs) with five different sludge stabilization treatments: anaerobic digestion, aerobic digestion, dehydration, composting, and lagooning. Results demonstrated that the distribution ratio of metabolites and parent compounds in influent wastewater was correlated with their excretion rates, reflecting pharmaceutical consumption as their primary source to WWTPs. Fluoroquinolone and sulfonamide antibiotics were predominant in influent wastewater, while macrolide antibiotics were more prevalent in primary sludge, likely due to their higher hydrophobicity, which results in greater retention in sludge. Parent compounds dominated over metabolites in sewage sludge, with composting plants showing the highest removal efficiency and highest metabolization among all sludge stabilization technologies studied.

In this study, a novel task-specific deep eutectic solvent (DES) composed of dibenzoylmethane (DBM) and trioctylphosphine oxide (TOPO) in a 1:1 molar ratio was developed for selective lithium extraction. Unlike conventional DESs, the DBM/TOPO-DES is hydrophobic, enabling efficient liquid–liquid extraction by minimizing miscibility with aqueous solutions. Under optimized conditions—pH 12, 30 s of vortexing, room temperature, and a 2:1 aqueous-to-DES phase ratio—the system achieved over 99% lithium extraction efficiency. It also exhibited high extraction efficiency with EDTA as a masking agent for lithium in the presence of commonly co-existing ions such as Co(II), Cu(II), and Ni(II), typically present in LIB cathode materials. Lithium was efficiently back-extracted using 0.7 M HCl, and the DES maintained excellent performance across five extraction cycles, demonstrating its reusability. Compared to other DES-based approaches, this system combines rapid kinetics, high extraction efficiency, and a greener profile without compromising performance. Thermal analysis, phase behavior, and spectroscopic characterization confirmed the stability and formation of the DES. Overall, the DBM/TOPO-DES offers a sustainable and effective alternative to traditional solvent systems, advancing green chemistry principles and contributing to the efficient recovery of critical lithium resources from spent batteries.</div></div>","PeriodicalId":276,"journal":{"name":"Chemosphere","volume":"385 ","pages":"Article 144556"},"PeriodicalIF":8.1,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144595873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
