The application of hypochiorite and peroxide was studied in this paper, emphasis was put on the effect of alkalinity, hypochlorite and peroxide charge on bleach outcome. Results indicated that reed CM pulp responded well to hypochiorite and peroxide in a two-stage sequence. Under optimum bleaching conditions, more than 40 points in brightness gain (from 32% to78%) could be achieved with 8% hypochiorite and 2% peroxide. The strength characteristics of the pulp were significantly improved after bleaching, but...
