Open publisher page 0 citations

Abstract

Phenol aqueous solution was treated by microwave(MW)/H2O2 combined technology and the affecting factors were studied.Experimental results showed that the removal efficiency of phenol was low when microwave irradiation process and H2O2 oxidation were used separately.MW/H2O2 combined technology was favorable for enhancing the removal efficiency of phenol,with the enhancement factor of the first-order kinetics constant being around 5.98.The synergetic effect of MW/H2O2 combined technology was obvious.The co-existence of Fe2+ had significant influence upon MW/H2O2 combined technology,and Fe2+ increased the reaction rate.
