Abstract
The effect of activation and heat treatment of row red mud (a residue from bauxite refining) on the adsorption of phosphate (PO4-P) from its solutions was studied in parallel experiments. Effect of time, temperature, concentration of adsorbate was studied using batch experiments. The adsorption of phosphate follows Langmuir better than Freundlich adsorption isotherm. Reprecipitated and calcined red mud was found to be the most efficient activation processes for the raw red mud. These findings can be extended to the treatment of industrial effluents containing phosphates like that from phosphatic fertilizer plants.
