  • Method of peroxide bleaching of pulp using a peroxide decomposing inactivator
    Patent number: 5618385
    Abstract: Chlorine dioxide is used to stabilize hydrogen peroxide in bleach liquor at alkaline pH. This is thought to be aided by the destruction of enzymes (especially catalase) produced by bacteria. The method is useful for the reprocessing of pulps, especially when a de-inking stage is involved.
