摘　　要：以酸性浅源蓝BRL为降解目标,采用亚硫酸钠-Fe(Ⅱ)-溶解氧体系产生的硫酸根自由基(·SO4^-)降解酸性浅源蓝BRL脱色,比较了不同体系的降解脱色性能,考察了pH值、Fe^2+浓度、SO3^2-浓度、空气流量、酸性浅源蓝BRL的初始浓度对降解脱色的影响。结果表明,最佳的实验条件为:pH=5.0,Fe^2+浓度0.50mmol·L^-1,SO3^2-浓度1.25mmol·L^-1,空气流量0.60L·min^-1,污染物浓度60mg·L^-1。经过60min的降解,酸性浅源蓝BRL溶液的降解率可达到90.49%。The acid blue BRL was used as the degradation target,and the degradation of acid blue BRL by sulfate radical free radical(·SO4^-)which was produced by sodium sulfite-Fe(Ⅱ)-dissolved oxygen system was investigated,and compared different systems of decolorization performance.The effects of pH,ferrous concentration,sodium sulfite concentration,air flow and initial concentration of acid blue BRL for decolorization were investigated.The results showed that the best experimental conditions were as follows:pH=5.0,ferrous concentration was 0.50 mmol·L^-1,sodium sulfite concentration was 1.25 mmol·L^-1,air flow rate was 0.60 L·min^-1,and pollutant concentration was 60 mg·L^-1.After 60 min degradation,the degradation rate of acid blue BRL solution could reach 90.49%.
