摘要
采矿、冶金等工业活动导致水环境中砷污染形势日益严峻.通过饮用水和食物长期接触砷,会导致慢性砷中毒.水体中As(Ⅲ)具有毒性强、难去除的特点.二氧化锰(MnO2)由于具有同时氧化吸附去除As(Ⅲ)的能力而备受研究者关注.综述了近些年MnO2在去除砷方面的研究进展.基于材料结构不同,从二氧化锰、二氧化锰电极材料、金属掺杂二氧化锰、二氧化锰负载材料等几个方面总结了二氧化锰及其复合材料在氧化吸附去除As(Ⅲ)中应用,并对其未来发展进行展望.
Abstract
Mining, metallurgy and other industrial activities have led to an increasingly serious situation of arsenic contamination in the water environment. Long-term exposure to arsenic through drinking water and food can lead to chronic arsenic poisoning. As(Ⅲ) in water is highly toxic and difficult to remove. Manganese dioxide (MnO2) has received much attention from researchers due to its ability to remove As(Ⅲ) by simultaneous oxidation and adsorption. The research progress of MnO2 towards arsenic removal in recent years was reviewed. Based on the different material structures, the applications of MnO2 and its composites in the oxidative adsorption removal of As(Ⅲ) were summarized from various aspects such as MnO2, MnO2 electrode materials, metal-doped MnO2 and MnO2 loading materials, and their future development was also prospected.
