FIELD: chemistry.
SUBSTANCE: invention relates to the field of chemistry, namely to a method for the oxidation of organic dyes, which can be used to treat wastewater from textile, food, paper, printing, leather and cosmetic industries from dye residues. The method includes the use of vegetable peroxidase. The bleaching of dyes of the oxazine group is carried out in the joint presence of a 0.4 mM solution of hydrogen peroxide and the peel of the sugar beet root, at a temperature of 24°C and a pH value of 4.01 of a solution of the dye of the oxazine group.
EFFECT: effective method for wastewater treatment from residues of dyes of the oxazine group in a short period of time is provided.
