Abstract

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.

在聚合物吸附剂上去除U(VI)：最新进展和未来挑战

大力发展核能是解决核能清洁、高能量密度所带来的能源危机和环境污染的主要战略之一。铀作为主要的核燃料，不仅是陆地资源的短缺，而且对环境构成潜在威胁。为了解决这些难题，各种聚合物因其丰富的活性位点、高吸附效率、大表面积和可控的多孔结构而被广泛开发用于去除废水中的U（VI）或从海水中提取U（VI）。本文综述了各种含聚合物吸附剂（金属-有机框架（mof）、共价-有机框架（COFs）和其他聚合物）对海水或废水中U（VI）的去除研究进展。综述了不同改性方法、影响因素及U（VI）对这些聚合物的作用机理。最后，提出了目前各种高分子吸附剂在去除U（VI）方面存在的问题和未来的发展方向。本综述有望为高效聚合物吸附剂去除水中或天然海水中的铀提供参考。

期刊介绍： Two of the most pressing global challenges of our era involve understanding and addressing the multitude of environmental problems we face. In order to tackle them effectively, it is essential to devise logical strategies and methods for their control. Critical Reviews in Environmental Science and Technology serves as a valuable international platform for the comprehensive assessment of current knowledge across a wide range of environmental science topics. Environmental science is a field that encompasses the intricate and fluid interactions between various scientific disciplines. These include earth and agricultural sciences, chemistry, biology, medicine, and engineering. Furthermore, new disciplines such as environmental toxicology and risk assessment have emerged in response to the increasing complexity of environmental challenges. The purpose of Critical Reviews in Environmental Science and Technology is to provide a space for critical analysis and evaluation of existing knowledge in environmental science. By doing so, it encourages the advancement of our understanding and the development of effective solutions. This journal plays a crucial role in fostering international cooperation and collaboration in addressing the pressing environmental issues of our time.
