摘要
研究了金属铁对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 的还原降解与溶液初始 pH 值、初始浓 度和溶解氧等因素有关。氯离子能消除金属铁的钝化现象。金属铁表面附载的铜对2，4-DNT 的还原降解具有催化作用。
The reductive degradation of 2,4 - DNT by metallic iron was investigated. Experimental results showed that the reductive degradation of 2, 4 -DNT was influenced by initial pH, concentration and DO, etc. Cl^- could eliminate passivafion of metallic iron . Copper adhering to the surface of metallic iron could catalyze the reductive degradation of 2,4- DNT.
