摘　　要：以膨润土为载体,负载金属离子,制备了负载型改性膨润土脱色材料,采用电化学降解的方法,研究了不同离子负载的改性膨润土、染料废水初始p H值、催化剂的加入量、反应时间对染料废水脱色效果的影响。研究表明,铁改性膨润土、p H值为4、催化剂加入量为18g/L、反应10 min活性红染料废水脱色效果最好,脱色率达到98%。The degradation dyeing wastewater catalyzed by metal ion modified bentonite in the electrochemical reactor has been investigated. The effects of pH, the different metal ion and dosage of catalyst on the efficiency of the electrochemical degradation process were studied. It was found that the bentonite modified by Fe3＋ had the highest electrochemical catalytic activity for the electrochemical degradation dyeing wastewater in pH 4. Its color removal rate could reach up to 98%.
