Oxidation of selected dyes with H2O2 and NaClO in the presence of a Fe(II) ion catalyst
Aq. Acid Violet 1 and Direct Blue 74 solutions, 100 mg/L each, were each nearly 100% decolorized with 1 mg (HO2)-O-2/mg dye plus 5.0 and 2.5 mg FeCl2 at 251 and 60degreesC, resp. at pH 2-4. NaClO used at 0.2 and 1.25 mg/mg dye, resp., was as effective as H2O2.
