本文研究了砖红壤和红镶中的氧化锰对１０种有毒酚化合物的氧化降解作用及氧化锰与酚化合物之间的氧化还原动力学，结果表明，土壤中氧化锰对某些有毒酚化合物具有氧化降解作用，各种酚化合物氧化降解的难易与其本身性质和分子结构有关。土壤中的氧化锰的还原溶解和氢醒的氧化均符合一级反应动力学方程。介质ｐＨ的降低有利于反应的进行，两种土壤中的氧化锰还原溶解反应对［Ｈ￣＋］的级数为０．１６．氢醌除与氧化锰发生氧化还原反应外，还与土壤发生诸如吸附等其它作用，总的变化速率应是两方面的变化之和。
The oxidative degradation of 10 kinds of toxic phenolic compounds and the redox kinetics between manganese oxide and phenolic compounds were studied in this paper. The results showed that the manganese oxide in the soil had the potential to oxidize some of the toxic phenolic compounds Oxidative degradation, the oxidative degradation of various phenolic compounds with its own nature and molecular structure is difficult. The reduction and dissolution of manganese oxide and the oxidation of hydrogen in the soil all conform to the first-order kinetic equation. Reduction of the pH of the medium favors the reaction, and the order of [H ~ +] for the manganese oxide reduction-dissolution reaction in both soils is 0.16. In addition to redox reaction with manganese oxide hydroquinone, but also with the soil occurs such as adsorption and other effects, the total rate of change should be two changes and the sum of.
