For the removal of perchlorate anions from water, adsorption using anion-exchange resins has been generally used as the most suitable method. We have prepared mesoporous anion-exchange resins via simple functionalization of amine ligands with different numbers of functional groups, and used them for the removal of perchlorate anions from aqueous solutions. The physical and chemical properties of the prepared samples were measured using nitrogen adsorption-desorption measurement, elemental analyses, X-ray diffraction, and Fourier transform infrared spectroscopy. We also investigated equilibrium isotherms for the measurement of adsorption capacities and kinetic performances of the prepared samples. The prepared materials showed fast adsorption kinetic performances, and M-3N among the prepared materials exhibited high perchlorate adsorption capacity of 175.4mg/g compared with the results of the previous reports.
