Phosphate Removal from Aqueous Solution Using Fly Ash Modified with Fe-Cu Bimetal Oxide

Abstract:

In this work the adsorption of phosphate using the Fe-Cu bimetal oxide modified fly ash was studied. The experimental results showed that phosphate could be effectively removed in the pH range between 4 and 10. The removal percentage of phosphate reached maximum at pH 6.0. The adsorption of phosphate by the modified fly ash was rapid, and the adsorption percentage of phosphate could reach 91.20% in 5 minutes. The removal efficiency of phosphate increased with the increase of adsorbent dosage and the decrease of the initial concentration. The adsorption of phosphate could be described well by Langmuir isotherm, the Langmuir constant Q₀ was 26.03mg/g.
