Nitrate removal from aqueous solution by Arundo donax L. reed based anion exchange resin

► We prepare ALR-AE resin from Arundo donax L. reed by the amination reaction. ► We validate the competitive adsorption properties of the resin for various anions. ► We use this resin in three actual water samples. ► We validate the ion exchange mechanism by Raman, zeta potential and FTIR spectra. ► We use the hydrophyte based product for the treatment of water eutrophication.
