2/ZrO 2/SiO 2 Mesoporous Materials from Sulfate Solutions]]>

摘要

New nanostructured mesoporous materials of the composition TiO~(2)/ZrO~(2)/SiO~(2)were prepared by the template sol–gel method using a siloxane–acrylate emulsion as a template. The morphology and structure of these materials and their ability to take up U(VI) were studied. The influence of various factors (ZrO~(2)content, pH of solution) on the sorption properties was studied. The suggested materials allow efficient sorption of U(VI) from sulfate solutions with low U(VI) concentrations and can be used in final purification processes.
