Peroxide General approach Hydrogen peroxide (H2O2) (referred to simply as “peroxide”, stage designation P) can oxidise the specific chromophoric groups in the lignin (see Lignin-preserving or lignin retaining bleaching) resulting in the colour removal.1 However, in this bleaching process, H2O2 alone is not enough and also alkali (NaOH) is needed for the bleaching reactions. Since H2O2
