A study on microwave oxidation of landfill leachate-Contributions of microwave-specific effects

► pH has an insignificant effect on TOC removals and 550 W has a well performance. ► MOP has well removals of color, UV254, and TOC at 550 W/85 °C. ► TOC removals were higher at higher microwave setting (550 W vs. 128 W). ► The microwave-specific effects on TOC removal were usually synergistic in MOP. ► COD analyses showed persulfate decayed rapidly in either MOP or CHO treatment.
