摘　　要：使用氧化试剂HNO_3和H_2O_2对活性炭进行改性处理,考察了改性处理对活性炭催化性能的影响,并对改性前后的活性炭进行表征。结果表明,改性后活性炭催化活性提高,用HNO_3处理比H_2O_2效果好,活性炭活性不仅与氧化试剂有关,还与活性炭的原料来源有关。Activated carbon（AC） was modified by treatment with HNO3 and H2O2 and characterized, and its catalytic behaviors were investigated. The results showed that the treatment enhanced catalytic activity of activated carbon;activity of activated carbon treated with HNO3 was higher than that treated with H2O2. Activity of treated activated carbon was dependent not only on the oxidation reagents, but also on starting material of AC.
