英文摘要: Abstract(#br)This study explores the potential use of amine cross-linked reed (ACR) for removing nitrate, phosphate and Cr(VI) from aqueous in a fixed-bed column. Characteristics (surface area, pore structure, FTIR, Raman spectra, XPS, zeta potential and solid NMR) of ACR as well as anions laden samples were intensively investigated. Results indicated that FTIR, Raman and XPS of nitrate and phosphate laden ACR were quite different from those of Cr(VI) laden samples, which corresponded well to their adsorption properties. Tertiary amine group played the main role in uptake of nitrate and phosphate by electrostatic attraction. Characteristics of Cr(VI) laden samples indicated that a reduction of Cr(VI) to Cr(III) occurred on surface of ACR (this was also proved by the zeta potential...
