16 ppm of H2O2

In this paper, oxidation of red methyl (MR) - an azo in dye by UV / H2O2 was studied. The effect of solution volume and initial concentration was studied. Under optimal conditions, project a UV light through the bottom of the solution containing MR. The rate of color change is proportional to the increase of H2O2 concentration. After 50 minutes, the decolorization effect with 16 ppm H2O2 is 38%, slightly higher than the content of 14 ppm H2O2.
