摘要
The ability of red mud (RM) to adsorb disperse blue 2BLN from water was studied and the condition of adsorption process was optimized. The results showed that the microwave activated RM had good adsorption capacity. The adsorption process was in accord with Langmuir isotherm model. The saturated adsorption amount of disperse blue 2BLN by activated RM was similar to 45 mg/g. The factors that affected the adsorption process included dosage of RM, temperature, and pH value. The optimal condition was 40 degrees C, pH 3.0, 15 g/L RM and 30 min reaction time, under which the removal percentages of color, chemical oxygen demand and total organic carbon reached similar to 99%, 64% and 50%, respectively.
