Synthesized Magnetic Activated Carbon for Phosphate Removal from Aqueous Solutions

Abstract

  Background & Objective: Discharge of phosphorous into surface water causes excessive growth of algae and aquatic plants followed by Eutrophication in lakes and rivers. Thus eliminating it from water supply is important. The aim of the present study is application of magnetic activated carbon to remove phosphate from aqueous solutions. Materials & Methods: Effects of operational parameters such as pH, initial concentration of phosphate, adsorbent dose and reaction time to remove phosphate was investigate in a batch reactor. Results: Adsorption efficiency increased significantly by increasing the initial concentration of phosphate, reaction time, adsorbent dose and pH to 7. On the other hand, the maximum removal of phosphate (98.7%) occurred at 5 mg/L of phosphate concentration, pH=7, adsorbent dosage of 0.8 g/L and contact time of 30 min. Conclusion: The high efficacy of the adsorption process in this study showed that magnetic activated carbon had good capability in the removal of phosphate and can be used as an appropriate and new method for phosphate removal from aqueous solutions
