Removal of Phosphate from Aqueous Solution by Using Red Mud

Abstract:

Red mud has been used to develop effective adsorbents to remove phosphate from aqueous solution. The effects of different dosage, pH of solution and reaction time on adsorption have been examined in batch experiments. It was found that red mud samples show higher removal efficiency for phosphate. The results showed that phosphate removal efficiency was found to be 97 % with optimal reaction conditions initial phosphate concentration 100mg L−1, red mud dosage 10g L−1, pH 2.0, respectively. The phosphate removal efficiency of the red mud adsorbents decreases with increase of pH.
