摘要
以石墨为阳极、活性炭纤维(ACF)为阴极,电Fenton法氧化降解甲基橙溶液。结果表明,在甲基橙溶液浓度为4 mmol/L、pH值为3、电压为8 V、硫酸亚铁的浓度为0.2 mmol/L、反应时间为60 min时脱色率可达到98.12%,并且甲基橙氧化降解遵循一级反应动力学。
The methyl orange degradation was carried out by the electro-Fenton reaction which was composed of graphite anode and active carbon fiber（ACF） cathode.The results showed that the degradation rate of methyl orange could reach 98.12% when the contentration of methyl orange was 4 mmol/L,pH value was 3,voltage was 8 V,contentration of Fe2＋ was 0.2 mmol/L and the reation time was 60 min.The degradation of methyl orange followed first-order kinetics equation.
