| 摘 要： | 研究了零价铁对2，4-二硝基甲苯(2，4-DNT)的还原降解情况。实验结果表明，2,4-DNT的还原降解率与溶液初始pH值、初始浓度、溶解氧含量和铁粉投加量等因素有关。2，4-DNT在还原过程中先生成2-氨基-4-硝基甲苯(2A4NT)和4-氨基-2-硝基甲苯(4A2NT)，最后被还原成2，4-二氨基甲苯(2，4-DAT)。

| Abstract: | The reductive degradation of 2,4-DNT by zero-valent iron was investigated. Experimental results showed that the reductive degradation of 2,4-DNT was influenced by initial pH, concentration, DO and addition of iron powder. During the reductive process of 2,4-DNT, 2A4NT and 4A2NT represented intermediates, 2,4-DAT was formed via further reduction. |
