Abstract
The kinetics parameters of phenol oxidation by MnO2 on the surface of iron-manganese nodules at pH = 5,5±0,5 at temperature region from 293 till 353 K was described in this paper. The oxidation reaction runs by second order on phenol. At temperature region from 293 till 353 K the limited stage is chemical reaction. The activation energy of oxidation on the surface of iron-manganese nodules is equal 6,65 kJ/mol, and it is less than it’s one for oxidation on MnO2 surface (42,0 kJ/mol). The oxidation products are hydrohinon and less than 10 pier. % p-benzohinon.
