We have studied physico-chemical features of the sorption of U (VI) ions by composites based on montmorillonite and organomontmorillonite modified by nanosized iron. The electron microscopic study of the obtained materials is performed. The possibility of their use in the purification of groundwater with the use of modern environmental technologies is shown.
