摘　　要：利用自制的平板型光催化反应器,采用草酸铁/过氧化氢为光催化剂,考察了双氧水浓度、流量等因素对刚果红降解效果的影响。实验结果表明,溶液呈酸性有利于降解反应进行,但是和双氧水的投入量一样,存在最佳值问题,铁离子浓度增加和流量变大都有利于染料的降解。Ferrioxalate and hydrogen peroxide were chosen for photocatalyzers. The degradation reactions of Congo red were studied in the plate flat photocatalytic reactor which was fixed by ourselves. The effect of hydrogen peroxide content,Fe^3＋ iron content and pH were investigated. The result indicated that the degradation of dye prefer to the acidic aqueous environment .There were the optimum values for the amount of hydrogen peroxide. Increasing of the liquid flow rate and concentration of iron is benefit for dyes＂ destruction. Some reasionable advice are raised at last.
