微波诱导活性炭催化氧化降解罗丹明B研究

Microwave-assisted Active Carbon Degradation of Rhodamine B

以罗丹明B模拟有机染料废水,对微波诱导活性炭处理罗丹明B进行研究,分别考察了微波辐射时间、微波辐射功率、外加氧化剂双氧水用量、活性炭用量对罗丹明B降解效果的影响。实验结果表明:对于1000 mg/L的罗丹明B,p H值为2,微波辐射时间为40s,微波功率为640 W,双氧水用量为0.2 m L,活性炭用量为0.1g时,罗丹明B的去除率可以达到99.6%。

The effects of microwave radiation time, microwave radiation power, H202 volume, and carbon dosage on the degradation of Rhodamine B were investigated. The results indicated that degradation rate of 1000 mg/L Rhedamine B waste water got to 99.6% with 40 second when the active carbon was 0. 1g and 0. 2 mL 30% H2O2 was added and microwave power as 640 W in pH of 2.
