It contains high levels of organic matter, nitrogen, phosphorus, heavy metals, and other contaminants of environmental and health concerns, but landfill leachate could also be used to produce nutrient and energy. Here we review physical, chemical, and biological methods to treat landfill leachates. Methods include adsorption, membrane separation, coagulation and flocculation, ion exchange, air stripping, chemical precipitation, electrochemical oxidation, Fenton oxidation, ozonation, photocatalysis, activated sludge process, sequential batch reactor, rotating biological contactors, nitrification and denitrification, upflow anaerobic sludge blanket, phytoremediation, and bioremediation. We discuss the technical, social, economic and environmental benefits of removing contaminants, and of recovering nutrient and energy. Physicochemical methods remove 12–95% of chemical oxygen demand, 1–100% of ammonia nitrogen, 40–96% of metals, and 44–99% of color. Advanced oxidation processes remove 19–98% of the chemical oxygen demand, 12–85% of ammonia nitrogen, and 74–98% of total organic carbon. Biological methods remove 15–93% of the chemical oxygen demand, 43–97% of the biochemical oxygen demand, 14–100% of ammonia nitrogen, and 42–98% of phosphates. Optimized leachate treatment technology can recover 10–80% of nutrients and 0.1–7 kWh/m3 of energy.","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"81 1","pages":""},"PeriodicalIF":15.7,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143020590","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}

Here, we review the water treatment with composites including bacterial cellulose, with focus on synthesis and modification of bacterial cellulose and composites, and application in water treatment. Synthesis of bacterial cellulose can be done in static, agitated and bioreactor cultures. Composite materials include metal oxides, metal organic frameworks, polymers, graphene and magnetic materials. Applications comprise the removal of microplastics, heavy metals, oil, and organic and inorganic pollutants. Bacterial cellulose is biodegradable, biocompatible, and possesses customizable surface chemistry and structure, enabling exceptional pollutant removal. Surface modifications add functional groups such as hydroxyl and carboxylate groups, while reinforcement strategies improve mechanical and chemical properties. Composites exhibit pollutant removal efficiencies of up to 99.9% and oil separation stability of 99% even after 20–50 cycles. Mechanisms including adsorption, photodegradation, flocculation, and biodegradation are discussed.","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"9 1","pages":""},"PeriodicalIF":15.7,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142990875","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 gadolinium complexes are excreted in urine and then end up polluting wastewater, leading to gadolinium concentration increase in rivers, known as the ‘gadolinium anomaly.’ Here we studied gadolinium recovery from patient urine using ligand-associated organosilica media impregnated with N,N,N′,N′-tetraoctyl-diglycolamide, a chelating agent traditionally used in separating lanthanides from actinides in nuclear waste applications. Gadolinium-containing urine was acidified with nitric acid and tested in batch and packed bed column experiments. Sorbent media and precipitate solids were analyzed using advanced characterization tools. Results show that more than 85% of the gadolinium was recovered with a 12.8 mg g⁻1 sorption capacity. A two-cycle column study produced over 99% pure gadolinium through stripping, oxalic acid precipitation, and calcination. A binding mechanism with a 1:3 chelation and matching kinetics for a pseudo-second-order rate model can help design scaled-up systems.","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"32 1","pages":""},"PeriodicalIF":15.7,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142990874","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}

Here, we combined the preparation of a cyclodextrin-based supramolecular deep eutectic solvent and the extraction of spent coffee grounds by microwave irradiation in a single step. We tested two new solvents, randomly methylated-β-cyclodextrin:propylene glycol and hydroxypropyl-β-cyclodextrin:ethylene glycol, and compared the results with two classical solvents, chloride:urea (1:2) and ethanol/water 80/20 vol%. We also used classical Soxhlet extraction. We calculated the sustainability of the process using ComplexGAPI. Results show that the optimal one-step extraction conditions were 15 min of irradiation at 80 °C with the addition of 10 wt% water. Under these conditions, the two new solvents showed higher extraction yields of antioxidants and polyphenols than choline chloride:urea (1:2) or ethanol/water 80/20 vol%. Similarly, the half maximal effective concentration and gallic acid equivalent of the Soxhlet extracts were 5 and 3 times lower, respectively, than those obtained with hydroxypropyl-β-cyclodextrin:ethylene glycol (1:40) 10 wt% water. The composition of the extracts from the one-step process was similar to that of the Soxhlet extract. Sustainability analysis revealed low energy consumption, reduced unitary operations and less waste production.","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"52 1","pages":""},"PeriodicalIF":15.7,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142981157","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}

However, destruction of chemical weapons is challenging, notably in the Russian Federation due to the large scale and complexity of chemical weapons stockpiles, the diverse toxic agents stored under varying conditions, logistical and political obstacles, financial constraints, and the disposal process. Here we review the Russian Federation’s chemical weapons disposal program with an emphasis on the political context, declared chemical weapons stockpiles, methods for destruction, health and environmental issues, and nerve agents. We analyze stockpiles totaling nearly 40,000 tonnes of chemical agents across seven facilities, focusing on their composition, storage conditions, and destruction technologies. Methods such as neutralization, bituminization, and thermal destruction are compared. Environmental risks include arsenic migration and groundwater contamination near disposal sites. We observe the limitations of using bitumen salt masses as a safe disposal method.","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"56 1","pages":""},"PeriodicalIF":15.7,"publicationDate":"2025-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142917215","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}
