Treatment of Dye Wastewater by Zero Valent Iron Composited Organobentonite

Abstract:

Article Preview

A novel material, zero valent iron composited organobentonite (NZVI-OB), was synthesized to adsorb dye from wastewater and to degrade the dye for avoiding secondary pollution. The crystal structure was characterized with X-ray diffraction (XRD). The effect of initial Orange II concentration and reaction time on the removal of Orange II by the NZVI-OB was studied. And the removal mechanism of Orange II was discussed. The results show that the Orange II can be removed by NZVI-OB efficiently. The maximal adsorption amount is 112.66 mg/g. The iron can effectively degrade the organic compounds after adsorption pollution, the carbon contents of organic pollutions after catalyzed and oxidized by the iron are lowered to the 19% of the original.
