摘　　要：铀资源是国家核工业发展的重要战略资源,安全可持续铀资源供应是核电健康发展的关键。除铀矿资源外,绿色海水提铀技术是最有应用潜力的铀资源供应途径。吸附法是海水提铀和含铀废水处理的常见方法,面对复杂的海洋环境,设计和制备吸附量大、选择性高的吸附材料成为解决问题的关键,以高附加值的生物质基材料为铀吸附剂是一种新型的可持续发展策略。本文详细综述了生物质基铀吸附材料的分类、制备方法及其吸附性能,概括了生物质基吸附材料的研究现状和热点,基于研究现状,展望了未来高效生物质基吸附材料在海水提铀方面的发展方向和研究趋势。Uranium resources are an important strategic resource for the development of the country’s nuclear industry, and safe and sustainable uranium resource supply is the key to the healthy development of nuclear power.Except uranium ore resource, uranium extraction from seawater becomes the most potential way to provide uranium resource. Adsorption is a common method for uranium extraction from seawater and uranium-containing wastewater treatment. Facing the complex marine environment, the design and preparation of adsorbent materials with high efficiency and high selectivity is essential. It is a new sustainable development strategy to prepare high value-added biomass-based materials for uranium adsorption. The classification, preparation methods and adsorption properties of biomass-based adsorption materials were reviewed, the research status and hotspots of biomass-based adsorption materials are summarized. At the same time, the development direction and research trend of high-efficiency biomass-based adsorption materials in the future are forecasted.
