Abstract
Red mud prepared in the laboratory was activated using hydrochloric acid with concentrations from 2-4 mol/L, heat at 900°C and combined acid and heat at 900°C, and the respective yields evaluated. The physico-chemical properties of these samples were determined using pH, EC, XRF, XRD, SEM, TGA-DTA analyses and textural properties (isotherm type, BET surface area, pore size distribution, total pore volume, average pore size, external surface area, micropore volume, micropore area) determined by nitrogen gas adsorption-desorption. Acid activation reduces red mud quantity than by thermal means. Raw red mud showed a pH of 11.0, EC of 2.50 x 109 μS/cm, BET surface area of 13 m2/g, total pore volume of 0.063 cm3/g with the major oxides being Fe2O3, Al2O3, TiO2 and SiO2. It contain mesopores > macropores > micropores. All these properties are improved variably by acid and thermal activation. Acid modification increase alumina content but decreases that of iron. Conversely, heat treatment increase iron content but reduces alumina content. Combined acid and heat treated red mud shows high thermal stability than untreated and acid treated red muds. These results show that possible different applications of red mud can be achieved depending on modification conditions.
