新型抗生物污损型海水提铀材料研制及其性能研究

Recovery of uranium from seawater has received great attention because it is considered as the most challenging and also the "highest return" project of nuclear fuel resource exploitation. Due to the complex marine environment, the development of ocean-tolerant and anti-biofouling materials is a compulsory approach to advance the technology of uranium extraction from seawater. This project intends to use radiation grafting and chemical modification methods to modify the materials, which molecular fragments or metal nanoparticles that have a remarkable ability to inhibit biofouling in seawater are incorporated. In addition this project will establish a new method of preparing anti-biofouling materials for recoverying uranium from seawater. By studying the comprehensive performance of materials, material that has the most potential could be screened out for real seawater test. It will provide the necessary experimental basis for the development of materials that can be used for long-term and stable recovery of uranium from seawater.

“海水提铀”被认为是最具挑战性，也是“回报”最高的核燃料资源研发项目而备受重视。面对环境复杂的海洋体系，发展海洋耐受型和抗生物污损型的提铀材料是提高海水提铀技术的必经之路。本项目拟采用辐照接枝与化学改性的制备方法对提铀材料进行改性修饰，接枝对海水中常见的生物污损物具有较好抑制能力的分子片段或金属纳米粒子，建立新型抗生物污损提铀材料的制备方法，获取一系列新型抗生物污损型提铀材料。通过实验室的抑菌实验和提铀实验对材料的综合性能进行表征，筛选出性能优越的材料进行长周期的真实海水测试实验，并对其在真实海水中的提铀性能、抗生物污损性能、机械性能和循环利用性进行全面考核，总结规律，探索主要影响因素，为研制能够在海水中进行长期稳定提铀试验的提铀材料提供必要的实验基础。
