| Abstract: | The influential factors of xylanase pretreatment were studied.The xylanase pretreatment could improve hydrogen peroxide bleaching.The addition of surfactant and the removal of heavy metal ions were of beneficial to xylanase treatment. The brightness and viscosity of bleached eucalyptus KP was 88.83%SBD and 564ml/g respectively,through the bleaching sequence (QX)-O 1-I-O 2-P 1-P 2.The xylanase pretreatment could reduce the consumption of hydrogen peroxide. |
