锕系环境放射化学对于核废料尤其是高放废物的安全处理和处置至关重要,同步辐射技术尤其是X射线吸收谱学在解析锕系元素在不同介质表面的配位结构方面可以发挥关键作用,对于理解锕系元素在环境介质中的迁移转化行为意义重大.本文综述了近年来国内外利用X射线吸收谱学研究锕系元素环境化学方面的最新进展,主要包括锕系核素在不同地质条件下的迁移和转化以及微生物对核素迁移的影响等方面.
Actinides Environmental radiochemicals are crucial for the safe handling and disposal of nuclear waste, especially for high-level radioactive waste. Synchrotron radiation technology, especially X-ray absorptiometry, can play a key role in resolving the coordination structures of actinides on different media surfaces , Is of great significance to understand the actinide migration and transformation behavior in environmental media.In this paper, recent advances in the environmental chemistry of actinides using X-ray absorption spectroscopy are reviewed in this paper, including the actinide nuclides in different geology Conditions of migration and transformation and the impact of microorganisms on the migration of nuclides and so on.
