Microwave assisted oxidative degradation of sulfamethazine in water with hydrogen peroxide
微波辅助双氧水氧化降解水中磺胺二甲嘧啶

Using microwave assisted oxidative to degrade sulfamethazine (SM2) with hydrogen peroxide in the water, the impact factors of which were also studied. Experimental results show that the degradation effects of SM2 were not significant when only microwave irradiation was used. However, as hydrogen peroxide added, microwave irradiation can significantly promote the oxidation of SM2 using hydrogen peroxide, as well as improve the degradation efficiency. The rate of degradation and COD removal rate of 50 mg/L SM2 solution were 96.5% and 72%, respectively, under the conditions including microwave power of 900 W for 6 min, 0.25 mL of H2O2(concentration was 30%), pH of 4.
