The XRD patterns of both Fe-Al (0 min) and Fe-Al (30 min) are depicted in Fig. 1. It can be seen that the Fe-Al (0 min) and Fe-Al (30 min) exhibit symmetric reflections of five major peaks at 2θ values occur, i.e. 11.7°, 23.7°, 34.3°, 39.4° and 46.6°, which are related to the respective (0 0 3), (0 0 6), (0 0 9), (0 1 5) and (0 1 8) planes of typical layered structure [18]. It indicates that the layered double hydroxides materials have been successfully synthesized in our experiments. Compared with the Fe-Al

Fe(II)-Al(III) layered double hydroxides (Fe-Al LDHs) were prepared by the sono-assisted precipitation method and used for the removal of uranium (VI) from aqueous solutions. The application of ultrasound in the Fe-Al LDHs preparation promoted the formation of the hydrotalcite-like phase and improved the adsorption capacity of U(VI). Batch experiments were carried out to investigate the influence of solid-to-solution ratio, initial U(VI) concentration, initial pH, contact time and temperature on the U(VI) removal process. The experimental results indicated that the removal process of U(VI) cou...
