| Abstract: | The aspen kraft pulp was totally-chlorine-free bleached with laccase/mediator system and hydrogen peroxide.The results showed that laccase/mediator treatment can improved the delignification and brightness of pulp,which was consistent with the increase of the surface area of aspen kraft pulp fiber.The surface area of aspen kraft pulp fiber was determined by the adsorption of Direct Sky Blue 6B during the treatment of bleaching. |

| Keywords: | biobleaching laccase dye adsorption surface area |
