FIELD: methods of oxidation of phenol compounds by hydrogen peroxide in the presence of catalyst.
SUBSTANCE: oxidation is performed by hydrogen peroxide in the presence of heterogeneous catalyst in aqueous medium; catalyst is made on base of aluminum oxide containing horse-radish peroxidase and modified by chitosan polysaccharide matrix in medium with equimolar amount of oxidizing agent at atmospheric pressure and intensive mixing at rate of 400-500 rpm and automatic delivery of oxidizing agent at temperature of 20-50°C and concentration of phenol of 0.01-0.3 mole/l. Proposed method may be used for purification of industrial waste water from phenol compounds.
EFFECT: increased degree of conversion of oxidation of phenol compounds.
