The vigorous development of nuclear power is one of the main strategies to solve the energy crisis and environmental pollution due to clean and high energy density of nuclear energy. As the main nuclear fuel, uranium is not only the shortage of terrestrial resource but also pose potential threat to the environment. To figure out these dilemma, various polymers have been widely developed to remove U(VI) from wastewater or extract U(VI) from seawater due to abundant reactive sites, high adsorption efficiency, large surface areas and controlled porous structure. Herein, the recent advances concerning U(VI) removal from seawater or wastewater on various polymer-bearing adsorbents (i.e., metal-organic frameworks (MOFs), covalent-organic frameworks (COFs) and the other polymers) were summarized at large. The effect of different modification methods, influencing factors and interaction mechanism of U(VI) on these polymers were reviewed in details. Finally, the current problems as well as future direction of various polymer adsorbents toward U(VI) removal was provided. The review hopefully provides high-efficiency polymer adsorbents for the removal of uranium from aqueous solution or natural seawater.

聚合物吸附剂去除 U(VI)：近期发展和未来挑战


核电清洁、能量密度高，大力发展核电是解决能源危机和环境污染的主要策略之一。铀作为主要核燃料，不仅是陆地紧缺资源，而且对环境构成潜在威胁。为了解决这些困境，由于反应位点丰富、吸附效率高、表面积大和可控的多孔结构，各种聚合物被广泛开发用于去除废水中的U(VI)或从海水中提取U(VI)。本文对各种聚合物吸附剂（即金属有机骨架（MOF）、共价有机骨架（COF）和其他聚合物）从海水或废水中去除U（VI）的最新进展进行了概括总结。详细综述了不同改性方法的效果、影响因素以及U(VI)对这些聚合物的相互作用机制。最后，提出了各种聚合物吸附剂去除 U(VI) 的当前问题以及未来方向。该综述有望提供高效聚合物吸附剂，用于从水溶液或天然海水中去除铀。
