摘　　要：以搅拌釜为反应装置,直接染料靛蓝胭脂红(IC)为目标污染物模拟染料废水,比较了Mn2+、Fe2+、Cu2+、Zn2+、Ag+、Mg2+6种金属离子活化过硫酸钠降解IC的效果。研究结果表明Fe2+对过硫酸钠的活化效果最好。通过对Fe2+活化过硫酸钠处理IC的条件进行优化发现,当温度为25℃、p H为7. 3、IC质量浓度为200 mg/L、Na2S2O8浓度为0. 8 mmol/L、Fe2+的浓度为0. 8 mmol/L时,靛蓝胭脂红的脱色率可在5 min内达到100%。The effect of Mn^2 ＋,Fe^2 ＋,Cu^2 ＋,Zn^2 ＋,Ag^＋,Mg^2 ＋on the activation of sodium persulfate（PS） for the degradation of indigo carmine（IC） in a stirred tank reactor has been investigated. The experimental results showed that Fe^2 ＋had the best activation effect on PS. The conditions of IC degradation by PS activated with Fe2 ＋were investigated and it was found that the decolorization efficiency of the simulated IC dye wastewater reached 100% in5 min when the temperature,pH,IC concentration,PS concentration and Fe2 ＋concentration were 25 ℃,7. 3,200 mg/L,0. 8 mmol/L and 0. 8 mmol/L respectively.
