摘　　要：在酸性介质中，大洋锰结核可以被苯胺、苯酚很好的还原浸出，在该氧化还原反应中苯胺、苯酚可被氧化为对苯醌。这一机理为ＴＬＣ、ＵＶ－ＶＩＳ、ＩＲ分析手段所证实。实验表明，大洋锰结核的氧化能力强于纯的ＭｎＯ２，苯胺的还原性强于苯酚。In acid medium, ocean manganese nodules can be easily reduced and leached with aniline or phenol. In the oxidation-reduction reaction, aniline or phenol is oxidized to P-benzoquinone. The mechanism was verified by TLC, UV_VIS and IR. Experiments indicated that the oxidative ability of ocean manganese nodules is stronger than pure MnO 2 and the reductibility of aniline is stronger than phenol.
