In this study, we show that chlorine dioxide activated by 4% Hydrochloric Acid Solution (HCl) has the same bleaching effects as that by sulfuric acid (H2SO4). Chlorine dioxide is an important bleaching agent in ECF bleaching. Stable chlorine dioxide in conjunction with Hydrochloric Acid Solution (HCl) activation in a certain proportion can be applied in the process of pulp bleach with a bleaching result of environment friendly, positive brightness stability, low pollutant bleach and pulp brightness stability, not easy to reverse. By experiment of OD, ODED, ODQP bleach Triploid of Populus Tomentos with stable chlorine dioxide activated by sulfuric acid (H2SO4). Moreover, the result of the experiment can prove that principle of activation of HCl to ClO2 is similar to H2SO4 to ClO2, that is, to provide an acid environment for ClO2.
