微波诱导H_2O_2降解罗丹明B溶液的研究

Study on the Degradation of Rhodamine B by H_2O_2 Microwave Indution

研究了微波诱导H_2O_2降解罗丹明B的效果。主要考查了微波辐射时间、双氧水的投加量、罗丹明B初始浓度、溶液pH值、微波功率等因素对罗丹明B降解率的影响。实验结果表明:罗丹明B浓度为10mg/L,30%的双氧水2m L,800W微波辐射8min,罗丹明B的降解率可达88.3%;实验还发现,微波或双氧水单独作用于罗丹明B溶液,基本没有降解作用。

In this paper, Rhodamine B was degraded by H202 microwave induction. Main impacting factors of degradation rate were investigated including, the concentration of Rhodamine B , microwave radiation time, dosing quantity of H2O2, pH of slotion, microwave power. The results showed that Rhodamine B concentration of 10mg/L, 30% 2mL of H2O2, 800W microwave irradiation time for 8mins, the degradation rate of Rhodamine B could reach 88.3%. Aslo found Rhodamine B was not degraded by the action of microwave alone, or by the action of hydrogen peroxide alone.
