同步辐射X射线吸收光谱在环境矿物学中的应用

本文介绍了同步辐射X射线吸收光谱（XAS）在环境矿物学中的应用与进展，尤其是在矿物载体催化剂的环境催化活性研究、固-液界面的微观机制研究、毒性痕量元素在矿物中赋存状态的研究、核废料的矿物处置研究等方面的发展现状。最后指出，XAS对推动环境矿物学的发展、优化环境矿物材料和原料的工艺流程具有独特的优势，在我国还有待进一步加强其发展和应用。

Application of Synchrotron Radiation X-ray Absorption Spectroscopy in Environmental Mineralogy

The application of synchrotron radiation X-ray absorption spectroscopy (XAS) in environmental mineralogy and its progress are briefly introduced in this paper. Special reviews on the research status of the environmental catalytic activity of catalysts supported on minerals, mechanisms of solid-water interface reactions, chemical state of toxical trace elements in minera-logical structures and nuclear wastes treatment by minerals are given. Finally, it is indicated that XAS is one of the most useful analytical technologies for the development of environmental mineralogy and the optimum of environmental mineralogical materials processing procedures. It is believed that the application of XAS in environmental mineralogy in China must be paid more attention.
