Abstract：A bench scale experiment on degradation of DBP in water by using sodium carbonate (SPC) oxidation enhanced by microwave (MW) was conducted,and the impact factors were studied by single-factor and orthogonal tests with the focuses on the difference between the effect of "MW single" and that of "MW-enhanced SPC" as well as that of "water bath plus SPC″.The study found that the major parameters affecting DBP degradation by MW-enhanced SPC were:reaction temperature,reaction duration,SPC dosage and initial pH value;and the optimal condition was:SPC/DBP (molar ratio) =250,initial pH=12,reaction temperature =85 ℃C and reaction duration=40 min,under which,removal efficiency of DBP was up to 85.52％,moreover,a synergy effect existed between SPC and microwave.
