摘　　要：工业废水中过量或放射性I^(-)、IO_(3)^(-)的存在易引发人体甲状腺病变甚至致癌,同时危害生态环境,因此,去除废水中的I^(-)、IO_(3)^(-)势在必行。吸附、膜分离、化学沉淀是常用方法。近年来,为提高脱除效率,减少吸附剂再生过程造成的二次污染,电化学、光化学辅助吸附逐渐受到重视。在介绍上述方法基本原理的基础上,着重阐述了离子交换树脂、层状双氢氧化物、金属有机框架化合物、天然矿物材料、生物质材料、膜材料等含碘废水处理材料的研究进展,最后对未来研究方向进行了展望。Excessive or radioactive I^(-)and IO_(3)^(-)in industrial wastewater may cause thyroid lesions and even carcinogenesis.It does harm to the ecological environment.Therefore,it is imperative to remove I^(-)and IO_(3)^(-)from wastewater.Adsorption,membrane separation and chemical precipitation are the conventional methods.In recent years,in order to improve the removal efficiency and reduce the secondary pollution caused by the regeneration process of adsorbent,electrochemical and photochemical assisted adsorption have attracted attention of most researchers.In this paper,the basic principles of the above methods are introduced,and the progress of materials for treating iodine-containing wastewater such as ion-exchange resins,layered doublehydroxides,metal organic frame compounds,natural mineral materials,biomass materials and membrane materials are emphasized.Finally,the future research directions are prospected.
