摘要:

铀是核工业不可或缺的资源,而陆基铀矿资源含量有限且分布不均。因此,海水提铀(UES)对可持续能源生产具有巨大潜力。电容去离子(CDI)技术以其低能耗、工艺简单、对环境友好和高吸附效率而闻名,对UES具有重要潜力。本文回顾了CDI技术的发展历史、原理、分类和应用。在发展历史部分,我们简要介绍了CDI技术的早期发展,并强调了其在UES中的关键里程碑以及近期优化工作。在原理和分类部分,我们将CDI技术置于UES应用的背景下,进行了全面介绍。另外,在应用部分,我们重点介绍了CDI技术在UES中的当前应用。此外,本文详细阐述了CDI技术在UES中的当前研究现状及其在吸附性、选择性和经济效益方面的优势。在吸附性方面,CDI技术通过精心优化电极结构和材料选择,展现了其吸附铀离子的效率。在选择性方面,CDI技术通过灵活调控电极材料和操作参数,有选择性地提取铀,同时减轻了来自竞争离子的干扰,从而提高了提取效率。在经济性方面,CDI技术因其低能耗和经济性脱颖而出,促进了高效的铀提取,且在UES领域具有与替代方法相比的实质经济优势。最后,我们讨论了该技术在铀提取过程中的挑战因素(竞争离子、盐度、pH值和生物污损),旨在探讨使用CDI技术进行UES的可行性和经济效益,并为进一步优化和推广CDI技术在UES中的应用提供理论支持。此外,我们还致力于通过引入材料信息学来解决CDI在提铀过程中存在的一些当前挑战,并展望该问题的未来发展。本文为CDI技术在UES中的发展和工业进展提供了实用的见解,旨在为后续CDI海水提铀研究提供宝贵的参考,以促进海水资源的可持续利用。

Abstract:

Uranium is an indispensable resource for the nuclear industry, while land-based uranium mines are limited in content and unevenly distributed. Therefore, uranium extraction from seawater (UES) holds great potential for sustainable energy production. Capacitive deionization (CDI) technology, known for its low energy consumption, simple process, environmentally friendliness, and high adsorption efficiency, holds significant potential for UES. This paper reviews the development history, principles, classifications, and applications of CDI technology. In the section on development history, we provide a brief overview of the early development of CDI technology, emphasizing key milestones in its application to UES and recent optimization efforts. In the section on principle and categorization, we contextualize CDI technology within UES applications for a comprehensive introduction. Additionally, in the application section, we concentrate on current applications of CDI technology in UES. Furthermore, this paper elaborates on the current research status of CDI for UES and its advantages in terms of adsorptivity, selectivity, and economic benefits. In terms of adsorptivity, CDI technology demonstrates its efficiency in adsorbing uranium ions, achieved through meticulous optimization of electrode structure and material selection. With regard to selectivity, CDI technology selectively extracts uranium while mitigating interference from competing ions through adept modulation of electrode materials and operational parameters, thereby enhancing extraction efficiency. Economically, CDI technology stands out due to its hallmark features of low energy consumption and cost-effectiveness, facilitating high-efficiency uranium extraction and providing substantial economic advantages over alternative methods in the UES domain. Lastly, we discuss the challenge factors (competing ions, salinity, pH, and biofouling) of this technology in the uranium extraction process, aiming to explore the feasibility and economic benefits of UES by using the CDI technology and providing theoretical support for further optimization and promotion of CDI applications in UES. Additionally, we aim to address some of the current challenges of uranium extraction using CDI by incorporating materials informatics and providing an outlook on this matter. This paper provides practical insights into the development and industrial progress of CDI technology in UES, aiming to offer valuable references for the subsequent research on CDI seawater uranium extraction to contribute to the sustainable utilization of seawater resources.
