Studying the Adsorption Properties of Modified Red Mud towards Phosphate Removal from its Solutions

Ahmed M. Yousif, Michael Rodgers, and Eoghan Clifford
 

 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.

Index Terms—Adsorption, red mud, PO4-P, wastewaters.
