The use of polyacrylamide-aluminosilicate composites for thorium adsorption

► Montmorillonite (Mt), clinoptilolite (Z) and zeolite Y were encapsulated in PAAm. ► The adsorption of Th4+ on these composites was significant. ► PAAm-Mt/Z were reusable for Th adsorption. ► The Th4+ ions were selectively adsorbed in the presence of foreign metal ions.
