摘　　要：探讨了预处理和过氧化氢强化氧漂对氧漂浆性能的影响，结果表明：采用酶、螯合预处理能较多地提高氧漂的选择性和脱木素程度，而对漂后浆的白度影响较小。在氧漂过程中添加过氧化氢能大幅度提高预处理浆的白度，而浆的卡伯值和粘度下降较小。The effect of pretreatment and H2O2 reinforcement on the property of oxygen bleaching pulp wasinvestigated. The results indicated that pretreatment with enzyme or chelate agent could improve the selective degree of oxygen bleaching and deliginification, but have less effect on the brightness of bleached pulp.The brightness of pretreated pulp could be improved greatly after oxygen bleaching with H2O2, but theKappa value and viscosity reduced just a little.
