摘　　要：介绍了利用电厂粉煤灰作为催化剂 ,催化 H2 O2 氧化 CN-的研究情况 ,讨论了各种因素对 CN-去除率的影响。结果表明 ,粉煤灰具有良好的催化活性 ,能有效地催化 H2 O2 氧化 CN- 。该法可用于处理电镀、制革、焦化行业含 CN- 的工业废水 ,具有广阔的应用前景。The oxidation of CN - by H 2O 2 using fly ash from coal-fired power plants as catalyst was studied. The effects of various parameters on the removal rate of CN - were discussed.The results showed that fly ash has a satisfactory catalytic activity, and it can efficiently catalyze the oxidation of CN - by H 2O 2. The method can treat the industrial waste water containing CN - in electroplating, tanning and coking industry, and will have broad prospects.
