This invention discloses a poly(amylated oxime-ethyleneimine) modified foam-like mesoporous silica, its preparation, and its application, belonging to the fields of environmental energy chemistry and new materials technology. Firstly, using Pluronic P123 / mesotriene as a pore-forming / expanding agent and tetraethyl silicate as a raw material, foam-like mesoporous silica is obtained through hydrolysis, aging, high-temperature pore expansion, and calcination. After activation, epoxy-modified foam-like mesoporous silica is obtained through a silanization reaction. Subsequently, polyethyleneimine-modified foam-like mesoporous silica is prepared by reacting amino groups with epoxy groups. Then, it is reacted with acrylonitrile to obtain poly(acrylonitrile-ethyleneimine) modified foam-like mesoporous silica. Finally, it is reacted with NH2OH·HCl to obtain poly(amylated oxime-ethyleneimine) modified foam-like mesoporous silica. The poly(amylated oxime-ethyleneimine) modified foam-like mesoporous silica of this invention exhibits extremely high adsorption capacity and extremely fast adsorption rate for uranyl ions, and demonstrates high affinity, selectivity, and good reusability, making it applicable to large-scale seawater uranium extraction projects.
