铁基金属-有机骨架及其复合物高级氧化降解水中新兴有机污染物

新兴有机污染物(Emerging organic contaminants,EOCs)是对人体健康及生态环境具有潜在或实质威胁的新型化学污染物.由于其被频繁使用且能在水生生态系统中持久性存在而对水生生物健康和安全造成严重威胁,故引起大众越来越多的关注.以活性污泥法为代表的传统水处理工艺通常不足以消除这些新兴有机污染物....

Elimination of Emerging Organic Contaminants in Wastewater by Advanced Oxidation Process Over Iron-Based MOFs and Their Composites

The emergence of emerging organic contaminants(EOCs)has attracted increasing attention due to their wide distribution and persistence in aquatic ecosystems,as well as the potential threat to the health and safety of aquatic organisms.Traditional water treatment processes represented by activated sludge processes are generally insufficient to eliminate these persistent pollutants.For efficient removal of EOCs,advanced oxidation technology based on new materials is one of the most important advanced treatment technologies.Fe-MOFs and their composites have been widely used in many fields,especially in the catalytic oxidation of pollutants in wastewater.With the aid of the improvement of synthesis methods,post-synthetic modification and being composited with specific functional materials,Fe-MOFs can be used to effectively improve the adsorption performance,enhance the light absorption characteristics,and promote the effective separation of charge carriers.The review focuses on the progress of advanced oxidation processes(photocatalysis,Fenton-like reaction and sulfate radical(SO₄^-·)mediated oxidation)of Fe-MOFs and their composites to remove emerging organic contaminants in wastewater.As well,the opportunities and challenges of Fe-MOFs in the field of EOCs removal are proposed.
