摘　　要：研究了芬顿体系对于水溶液中蒽醌染料活性艳蓝KN-R的氧化去除效果,反应30 min后,在H2O2浓度0.5 mmol/L、Fe(Ⅱ)初始浓度0.05 mmol/L、pH=3.0的条件下,初始质量浓度为20 mg/L的活性艳蓝模拟废水去除率达到96.2%.H2O2浓度和Fe(Ⅱ)初始浓度较高时,反应过程中的Fe(Ⅱ)浓度维持在一个较低的水平,活性艳蓝的降解速率较快.芬顿体系中的H2O2和Fe(Ⅱ)浓度一定时,随着活性艳蓝初始质量浓度的增加,其去除率逐渐降低.The oxidative removal of anthraquinone dye Reactive Brilliant Blue KN-R in aqueous solution by Fenton＇s reagent was studied. After 30 min, 96.2% removal rate of Reactive Brilliant Blue in water （pH= 3.0） was achieved when the H2O2 dosage, initial concentrations of Fe（Ⅱ） and Reactive Brilliant Blue were 0.5 mmol/L, 0.05 mmol/L and 20 mg/L, respectively. A relatively low concentration of Fe（ Ⅱ ） was maintained dur- ing reaction process when H2O2 and Fe（Ⅱ） were added with high concentration, and thus Reactive Brilliant Blue was degraded quickly. With increasing the initial concentration of Reactive Brilliant Blue, its removal rate reduced gradually when the initial concentrations of H2O2 and Fe（ Ⅱ ） were certain in Fenton＇s system.
