摘  要:
进行了芬顿体系催化氧化降解染料甲基橙水溶液的研究,考察了pH值、Fe~(2+)和H_2O_2投加量、温度等因素在对甲基橙降解率的影响。结果表明:在室温20℃下,pH=3.0、[Fe~(2+)]0=0.4mmol/L、[H_2O_2]0=1.2mmol/L的条件下,反应30min后,甲基橙水溶液(30mg/L)的降解率达到90%。升高反应温度,有利于Fenton体系中甲基橙的降解,但影响并不显著。结果可为利用芬顿体系处理含甲基橙的印染废水提供理论依据。

摘  要:
The degradation of methyl orange(MO)in aqueous solution by Fenton's reagent was studied.The influence of various factors,such as pH values,concentrations of Fe~(2+)and H_2O_2 and the reaction temperature on the effect of MO removal was investigated.The results show that the degradation rate of MO(30 mg/L)is over 90%after 30 mins under the experimental conditions of pH=3.0,[Fe~(2+)]0=0.4 mmol/L,[H_2O_2]0=1.2 mmol/L at room temperature(20 ℃).Increasing the reaction temperature was beneficial for the degradation of MO,but the effect is not obvious.This study provides a theoretical basis for the treatment of dyeing and printing wastewater containing MO by Fenton system.
