Abstract

The aim of this paper was to investigate adsorption of cupric ionin wastewater with a new type of adsorbent, namely natural oxidized celluloses(NOCs), whichwas synthesized in a specialselective oxidation system withraw cellulose. The characterization of NOCs was investigated by FTIR and the morphology of NOCs was examined with scanning electron microscope. The effects of adsorbent dosage, pH, temperature, initial concentration and adsorption time on the adsorption efficiencywere explored on the adsorption efficiency. The results demonstrated thatthe removal efficiency of Cu2+ could be achieved as high as 99% under the conditions of the temperature 25°C, the Cu2+ concentration 100mg•l-1, pH 5~6 in solution, dosing 0.175gNOCs with one hour’s shaking. Adsorption isothermal studies also revealed that the adsorption process of Cu2+ was well fitted with the Freundlich and Langmuir type adsorption isotherm. In conclusion, because of the raw cellulose is the most abundantbiomasson the earth as well as a renewable and biodegradable material, NOCs may have broad application in wastewater treatment industry as a new adsorption material in the future.
