Аннотация

The article discusses the mechanisms of interaction of ozone with aqueous solutions of organic dyes. Two different dyes with different types of chromophore systemwere investigated: azo dye and thiazine dye. A detailed methodology for performing experimental studies makes it possible to accurately dose ozone into the reaction mixture. The data of experimental studies are presented indicating the effectiveness of the use of ozone for the destruction of dyes in aqueous solutions. The specific doses of ozone were established to reduce the color intensity of the studied dye solutions to standard values.
