摘　　要：采用吸附材料处理铀矿开采、加工及乏燃料后处理产生的含铀废水和吸附海水中的铀为当前研究热点。吸附材料与铀的结合主要是通过官能团的配位作用,其中偕胺肟基团由于对铀具有特异性响应,而表现出优异的吸附选择性。本文归纳了偕胺肟基团的制备方法,对氰基-羟胺法进行了详细介绍。从吸附材料形态和功能角度详述了现阶段偕胺肟单官能团吸附材料的研究进展,同时对-NH2和-AO或-COOH和-AO的双官能团协同吸附进行了介绍,并对偕胺肟基团与铀的配位机理进行了简要分析,最后对偕胺肟基吸附材料的基底材料选择、制备方法和特殊功能性进行了展望。Researching of adsorbent materials is a hot topic in the fields of uranium mining,processing and treatment of uranium-containing wastewater from spent fuel reprocessing and uranium extraction from seawater.The binding of adsorbent materials to uranium is mainly via the coordination of functional groups,among which the amidoxime groups exhibit excellent adsorption selectivity due to their specific interaction with uranium.In this paper,we summarize the preparation methods of amidoxime groups,especially the cyano-hydroxylamine method is introduced in detail.The progress of the present research on the mono-functional adsorption materials of amidoxime is elaborated from the perspective of the morphology and function of adsorbent materials,while the bifunctional synergistic adsorption of-NH2and-AO or-COOH and-AO is introduced,and the coordination mechanism of amidoxime groups with uranium is briefly analyzed,and finally,trends are prospected in view of the selection of substrate materials,preparation methods and special functionalities of amidoxime-based adsorbent materials.
