摘要：
Kinetics of oxidation of phenols on the iron-manganese concretions in the temperature range 293–353 K at pH 5.5±0.5 was studied. Reaction of oxidation on the iron-manganese concretions has the second order by phenol. It is characterized by low activation energy, 17.5 kJ mol−1, due to the catalytic action of iron(III) oxide. Lower rate of oxidation of phenols on the iron-manganese concretions is observed as compared to oxidation on the pyrolusite surface. It occurs because of the decrease in MnO2 concentration in the ironmanganese concretions.
