▎ 摘　　要

NOVELTY - Material, is claimed. The material is porous material in which surface phosphate groups coordinate with iron ions, and the uranium adsorption material is prepared by reacting porous material with phosphoric acid groups on surface and iron salt in strongly acidic environment. USE - The material is useful for adsorption of uranium (claimed). ADVANTAGE - The material has large specific surface area, high adsorption capacity and good selectivity. The method: is simple and economical; and high in efficacy. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing material, comprising (i) adopting calixarene, Lewis acid, crosslinking agent, and organic solvent reaction to obtain hypercrosslinked calixarene porous polymer, (ii) adding hypercross-linked calixarene porous polymer into concentrated phosphoric acid for reaction, hydrolyzing and filtrating to obtain porous uranium adsorption material with phosphoric acid groups on surface, (iii) heating and reacting porous uranium adsorption material with phosphoric acid groups on surface with iron salt for specific period of time under concentrated acid environment, and (iv) completing reaction, sucking solid product through Buchner funnel, washing and drying to obtain porous polymer uranium adsorption material.
