Abstract

Abstract: In this study, a new hot oxygen stream modification and regeneration method was used to modify sepiolite (H/sepiolite) and remove the organic dye auramine O. It was found that the unit adsorption capacity of modified sepiolite exceeded 200 mg/g at the modification temperature and time of 550 ℃ and 1 h and an oxygen flow of 6 L/min. The characteristics of static adsorption of auramine O over H/sepiolite were studied and fitted by relative models, and the results showed that the Langmuir isotherm and pseudo-first-order kinetic could describe the adsorption behavior and kinetics of H/sepiolite. The effects height-diameter ratio (the ratio of packing height to inner diameter of adsorption column), flow rate and concentration of dye solution on dynamic adsorption were studied, the results displayed that about 55 BV(bed volume), 42 BV and 45 BV of wastewater ware treated on the condition of height-diameter ratio = 2.5, the dye flow rate = 6 BV/h and the dye initial concentration = 200 mg/L, respectively. The hot oxygen stream was used to regenerate the saturated H/sepiolite, the regeneration rate could reach nearly 100% at the gas flow rate of 6 L/min, regeneration temperature of 550℃, and regeneration time of 20 min.
