In this study, a new type of phosphorylated chitosan-supported nano iron (CSP/Fe-0) composite material. CSP/Fe-0 had a high adsorption rate (99.25%) and a maximum adsorption capacity (627.34 mg g(-1)) when the conditions were pH = 6, 308.15 K and 12 h. CSP/Fe-0 had a specific surface area of CSP/Fe-0 was 6.02 m(2) g(-1), and has a mesoporous structure with more active sites (average pore size is 9.67 nm). The primary mechanism may be the complexation of U(VI) with abundant -OH, -NH2, P=O on the surface of the material and the reduction of nanoscale zero-valent iron. Therefore, it is indicated ...
