Application of ozone and hydrogen peroxide for decoloration of dyes-comparison study

摘要

Chemical oxidation methods are used basically for toxic and biological resistant substances containing wastewaters. Ozone and hydrogen peroxide may be named ,,ecological agents'' because they give environment friendly oxidation products. Organic dyes, that are very stable in water environment, can be removed by chemical oxidation. We compared ozone and hydrogen peroxide oxidation abilities to decoloration of dyes.
