In this work, a new material containing chitosan(CS)-hexachlorocyclotriphosphazene (HP) composite was synthesized with polyphosphoric acid as the cross-linking agent for the effective removal of uranium(VI) from aqueous solution. The prepared material was characterized by FTIR, EDS, SEM, BET and XPS. According to batch experiments, its adsorption equilibrium (Qe = 398.8mgg−1) was reached within 50min at pH 6.0. The adsorption process could be well fitted to the pseudo-second-order model and the Langmuir model. The thermodynamic analysis indica...
