摘要
研究了锰离子对蔗渣浆和竹子浆过氧化氢漂白的影响。研究结果表明,随着Mn2+含量的增加,残余H2O2迅速减少,过氧化氢漂白浆的白度逐渐降低,而卡伯值逐渐提高。但一定量Mn2+的存在有利于漂白浆粘度的提高。
The effect of Mn2+ content on the hydrogen peroxide bleaching of bagasse and bamboo pulps was investi-gated. The results indicated that,with increasing of Mn2+ content,residual H2O2 and brightness of peroxide bleached pulps decreased, Kappa number of the pulps increased. But the existence of a contain amount of Mn2+ was favorable for increase of the pulp viscosity.
