微波辅助Fe-H_2O_2联合处理罗丹明B废水

Treatment of Rhodamine B Wastewater by Microwave-assisted Fe-H_2O_2 Combined Process

对微波辅助Fe-H2O2联合处理罗丹明B废水进行了研究,分别考察了废水pH、H2O2加入量、铁粉加入量、初始罗丹明B质量浓度以及反应时间等因素对罗丹明B去除率的影响。实验结果表明,对于100 mg/L的罗丹明B废水,当加入50 mg/L铁粉、10.0 mL/L H2O2,反应12 min后,罗丹明B去除率达到98.7%,并且拓宽了反应的pH范围。

Rhodamine B Wastewater was treated by microwave-assisted Fe-H2O2 combined process.The factors affecting the removal rate of rhodamine B were investigated.When the rhodamine B mass concentration is 100 mg/L,the iron powder dosage is 50 mg/L,the H2O2 dosage is 10.0 mL/L and the reaction time is 12 min,the removal rate of rhodamine B is 98.7%,meanwhile,the range of the reaction pH is enlarged.
