Iron-modified biochar, synthesized from agricultural waste, is proposed as an efficient and sustainable media for removal of ciprofloxacin and amoxicillin from wastewater. Iron-modified biochar was synthesized using a simple pyrolysis process with corn and ferrous sulfate as feedstock. Adsorbents were characterized by fourier transform infrared spectroscopy, X-Ray diffraction, and scanning electron microscopy. Removal performance of antibiotics was evaluated under different conditions, including antibiotic dosage, concentration of hydrogen peroxide, pH, and amount of humic acid. The results demonstrated high removal efficiencies of 87% for ciprofloxacin and 83% for amoxicillin within 25 min. Mechanistic studies revealed the generation of hydroxyl radicals (<sup>•</sup>OH) and singlet oxygen (<sup>1</sup>O₂), and confirmed the activation of hydrogen peroxide in the system. These findings highlight the potential of iron-modified biochar as a sustainable and effective catalyst for antibiotic removal, offering a promising solution for reducing pharmaceutical contamination in wastewater.</p></div>","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"23 1","pages":"27 - 32"},"PeriodicalIF":15.0,"publicationDate":"2024-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142598235","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}

Long-lived photo-oxidants are reactive species formed when the chromophoric dissolved organic matter absorbs sunlight, and they are involved in the degradation of contaminants. Previous works identified long-lived photo-oxidants with phenoxy radicals, which could be formed upon oxidation of natural phenols by the excited triplet states of chromophoric dissolved organic matter. Here, we generated reactive phenoxy radicals by direct ultraviolet-A photolysis of 2-nitrophenol and 4-nitrophenol. We measured the second-order rate constants for reaction of these phenoxy radicals with 2,4,6-trimethylphenol, a model electron-rich phenol. Results show rate constants of 9.39 × 10<sup>8</sup>(M<sup>−1</sup>s<sup>−1</sup>) for the 2-nitrophenoxyl radical, and 1.56 × 10<sup>8</sup>(M<sup>−1</sup>s<sup>−1</sup>) for the 4-nitrophenoxyl radical. These values are slightly lower than the typical rate constant of the reaction between 2,4,6-trimethylphenol and the excited triplet states of chromophoric dissolved organic matter, of 3 × 10<sup>9</sup>(M<sup>−1</sup>s<sup>−1</sup>). This means that 2,4,6-trimethylphenol would not be degraded to comparable extents by the excited triplet states of chromophoric dissolved organic matter and by long-lived photo-oxidants, if long-lived photo-oxidants were generated solely by the triplet states of chromophoric dissolved organic matter. Overall, findings suggest the occurrence of new pathway involving the direct photolysis of organic matter phenols that generates long-lived photo-oxidants.</p></div>","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"23 1","pages":"21 - 26"},"PeriodicalIF":15.0,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10311-024-01786-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142580235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their small size allows them to easily disperse across different ecosystems and enter the marine food chain, increasingly threatening coral ecosystems. This study hypothesizes that exposure to polyethylene microplastics alters the structure of coral skeletons. To test this, <i>Briareum violacea</i> corals were cultured under controlled conditions and exposed to polyethylene microplastics at concentrations of 0, 5, 10, 50, 100, and 300 mg/L for seven days. Skeletal structures were analyzed using X-ray diffraction, while inductively coupled plasma mass spectrometry was employed to assess changes in skeletal solubility and measure total calcium ion concentrations in seawater. The results revealed a transformation of coral skeletons from aragonite calcium carbonate crystals to amorphous calcium carbonate, as observed through X-ray diffraction analysis, with polyethylene microplastics causing this transformation to begin at a concentration of 10 mg/L. Additionally, skeletal solubility increased by 7.4-fold, as inferred from calcium ion concentrations measured by inductively coupled plasma mass spectrometry. Here we demonstrate that polyethylene microplastic exposure directly drives the degradation of coral skeletons, emphasizing the urgency of mitigating plastic pollution to safeguard coral ecosystems.</p></div>","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"23 1","pages":"7 - 11"},"PeriodicalIF":15.0,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142561972","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}

We specifically explore biogas applications in rural and industrial settings, assess the environmental impacts, and discuss the regulatory landscape with insights from China and Europe.
