Biochar has emerged as a promising adsorbent for antibiotic removal, but its performance is often limited by low capacity and slow kinetics, especially for high-molecular-weight antibiotics. In this study, a hierarchical porous Fe-supported biochar (HPFeBC) was synthesized via one-step pyrolysis of pine sawdust using Fe(NO₃)₃ as both activator and template. The obtained HPFeBC exhibited a well-interconnected pore structure with a high surface area (417.23 m²/g) and enhanced mesoporosity, significantly improving mass transfer and accessibility of adsorption sites. HPFeBC demonstrated exceptional adsorption performance for both low-molecular-weight antibiotic tetracycline (TC) and high-molecular-weight antibiotic tylosin (TYL), with maximum capacities of 361.23 mg/g and 173.61 mg/g, respectively. Notably, HPFeBC achieved rapid adsorption equilibrium within 5 mins for TC and 30 mins for TYL, far surpassing commercial adsorbents. The adsorption process followed the pseudo-second-order kinetics and the Freundlich isotherm model, and thermodynamic analysis confirmed the spontaneous and endothermic nature of adsorption. The adsorption mechanism involved pore filling, π-π interactions, hydrogen bonding, surface complexation, and limited redox reaction. HPFeBC also exhibited excellent stability over a wide pH range, strong anti-interference ability, and good reusability. Overall, the synthesis HPFeBC can act as an effective candidate for rapid and efficient removal of antibiotics from water.</div></div>","PeriodicalId":11725,"journal":{"name":"Environmental Technology & Innovation","volume":"41 ","pages":"Article 104699"},"PeriodicalIF":7.1,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145798426","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}

The results showed that two legacy PFAS demonstrated independent positive associations: PFOA (OR: 2.14, 95 % CI: 1.18–4.08) and PFOS (OR: 1.92, 95 % CI: 1.16–3.32).

This study proposes an innovative one-reactor system for dual nutrient recovery, combining P chemical precipitation and ammonia (NH₃) absorption into acid via gas-to-liquid membrane stripping (GLMS), using elevated temperature (T) and alkaline pH to promote both struvite formation and NH₃ volatilization. Laboratory-scale batch tests were performed using synthetic wastewater to evaluate the integrated technology feasibility and understand the effects of pH (7.3–10.0), T (20–50°C), and feed concentration (1.0–3.0 gNdm⁻³; 0.4–1.2 gPdm⁻³) on recovery performance and product purity. The system achieved up to 99.3 %P and 93.1 %N recovery, with GLMS increasing N recovery by 37.0 ± 24.6 % compared to struvite precipitation alone, though the dominant N recovery pathway (crystallization vs. absorption) depended on the applied operational conditions. Struvite was the dominant P phase at pH ≤ 9.0, whereas highly alkaline and thermal conditions, together with a higher feed concentration, affected product purity and homogeneity. Conversely, elevated pH and T were the main drivers of NH₃ volatilization, showcasing the mutual effect of NH₃ stripping and struvite precipitation. Operation under moderate conditions (pH 8.0–9.0, 38–41°C) yielded high-purity struvite (∼100.0 %), &gt; 93.0 %P and &gt; 40.0 %N recovery effectiveness. This study demonstrates the feasibility of integrating struvite precipitation with NH₃-oriented GLMS in a compact system for enhanced nutrient recovery from wastewater, enabling the production of two wastewater-derived fertilizers while reducing spatial footprint, energy consumption, and chemical demand compared to conventional two-stage N and P recovery systems.</div></div>","PeriodicalId":11725,"journal":{"name":"Environmental Technology & Innovation","volume":"41 ","pages":"Article 104686"},"PeriodicalIF":7.1,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145749172","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}

These materials were characterized and subsequently deployed to remove 2,4-dichlorophenoxy acetic acid from model solutions at 50 ppm concentration at pH 7. Shrimp shell and shrimp hydrochar composites were typically mesoporous but shrimp chitin composites were microporous. Specific surface area ranged from 1224 m²/g to 1974 m²/g. Surface nitrogen peaked at 2.94 at% with amine, amide and imide function predominating. The largest specific surface area and greatest nitrogen content of composites was more than 56 % and 5 times greater than the pristine greenheart adsorbent. Nitrogen functionality was uniformly distributed on the composite surface implying that there was homogeneous combination of the co-valorized feedstocks. The shrimp-chitin-greenheart composite was most efficient at removing 2,4-D with a maximum adsorption capacity of 101 mg/g.
