Abstract:
The degradation of phenol in aqueous solution with the combination of microwave and ozone(MW/O3)was studied with laboratory-scale experiments.Effects of ozone dose,pH value,initial phenol concentration and reaction temperature on the reaction kinetics were investigated.In all cases,the degradation of phenol follows a pseudo-first-order kinetics relation.MW/O3 combined technology is favorable for enhancing the removal efficiency of phenol,with the enhancement factor of the first-order kinetics constant being around 3.6.Experimental results showed that the synergetic effect of MW/O3 combined technology was obvious and up to 99 % of phenol was removed after 30 min reaction with initial phenol concentration of 100 mg·L-1,ozone dose of 1.1 mg·min-1,pH value of 9—11,and reaction temperature of 25℃.
