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.
