| 摘 要： | 有机砷作为饲料添加剂在家禽养殖中被广泛使用，并伴随着家禽粪便大量进入环境中. 进入环境后有机砷容易被生物降解或(光)化学氧化转化为剧毒的无机砷，危害环境和人体健康. 因此，高效处理有机砷污染受到广泛关注. 金属有机框架(metal organic frameworks, MOFs)材料因其具有孔隙率和比表面积大、孔道尺寸可调、易功能化改性和材料性能可定制等特点，在水体污染物的去除中展现了良好的应用前景. 本文综述了目前MOFs材料作为吸附剂去除水环境中有机砷的最新研究进展，介绍了吸附有机砷MOFs材料的种类、制备方法和吸附性能，总结了MOFs材料吸附有机砷的关键影响因素，并归纳了不同类型MOFs材料吸附的再生方法和稳定性. 最后，指出了当前MOFs存在的技术缺陷及限制工程应用的关键因素，并提出相对应的建议及解决措施.

| Abstract: | Organic arsenic compounds are widely used in poultry farming as feed additive, resulting in the discharge of a large number of poultry manure into the environment. After entering the environment, organic arsenic compounds can be easily biodegraded or photochemically oxidized into highly toxic inorganic arsenic, which is even more harmful to the environment and human health. Therefore, effective treatment of organic arsenic pollution has risen widely concern. Metal-organic frameworks (MOFs) have shown promising application prospects in the removal of pollutants in water due to their large porosities, specific surface area, adjustable pore size, easy functionalization and customizable material properties. In this paper, the recent progress of organic arsenic removal by MOFs through adsorption are reviewed, and a summary of the variations, preparation methods and adsorption properties of MOFs materials is provided. The effects of various key factors on the adsorption performance of MOFs materials and the regeneration adsorption properties and the stability of various types of MOFs are summarized. Finally, the technical defects of the current MOFs and the key factors restricting engineering application are discussed, and corresponding suggestions and solutions are proposed. |
