摘要：

In this work, solar light induced photoreduction of water-soluble U(VI) was realized with metahnol under anaerobic conditions at the optimal pH around 5.00. TEM, XPS, and XRD analyses prove that U(VI) is removed from the aqueous solution by forming insoluble brown uranium precipitates containing uranium dioxide (UO2). The photoreduction approach shows obvious selectivity for the removal of U(VI) and the efficiency (95.47%) is comparable to that of the photocatalytic reduction method (99.35%) while only uranium sediments are formed with the photoreduction approach. Photoreduction offers an efficient approach for the rapid removal of U(VI) from the aqueous solution.
