微波诱导H_2O_2降解甲基橙溶液的研究

Study on the degradation of methyl orange by H_2O_2 microwave indution

本文研究了微波诱导H2O2降解甲基橙的效果。主要考察了甲基橙初始浓度、溶液p H值、双氧水的投加量、微波辐射时间等因素对甲基橙降解率的影响。实验结果表明:甲基橙浓度为5mg/L,p H值为4,0.132mol/L的双氧水12m L,微波辐射时间为13min时,甲基橙的降解率可达100%。实验还发现微波或双氧水单独作用于甲基橙溶液,基本没有降解作用。

In this paper, methyl orange was degraded by H2O2microwave induction. Main impacting factors of degradation rate were investigated ,including the concentration of methyl orange, pH of slotion, dosing quantity of H2O2, microwave radiation time. The results showed that methyl orange concentration of 5 mg/L, the pH value of 4, 0. 132 mol/L 12 mL of H2O2, microwave irradiation time for 13 mins, the degradation rate of methyl orange could reach 100%. Aslo found methyl orange was not degraded by the action of microwave alone,or by the action of hydrogen peroxide alone.
