The Orange n decoloration reaction in the presence of various organic solvents with the HRP-H_2O_2 system was examined. In 5% organic solvent mixing aqueous solutions, the decoloration rates of Orange n were about 0.9-0.5 times of those in the aqueous solutions. Decoloration rate of Orange II decreased, as the concentration of organic solvent increases. The reaction of Orange n decoloration stopped at the 60% dimethyl sulfoxide concentration.
