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.
Key words: Triploid of populus tomentos, soda-AQ pulp, chlorine dioxide activated by H2SO4, chlorine dioxide activated by HCl, bleaching effects, ,
