摘要
研究了钼酸盐对桉木硫酸盐氧漂浆酸性 H2O2 漂白的改善效果，探讨了各种影响因素（钼酸盐用量、漂液 pH 值、H2O2 用量、氧强化的碱抽提和洗涤方式）对酸性 H2O2 漂白结果的影响。结果表明：添加少量的钼酸盐能有效地促进酸性 H2O2 的脱木素反应，提高脱木素效率，增加纸浆的白度。当钼酸盐用量为 0.1％ 时，脱木素程度比单纯的 H2O2 漂段提高 27.8％，白度增加 4.3％（ISO），而粘度的损失不大。
In this paper, effect of various conditions（molybdate charge,pH,peroxide charge,reinforced-alkali-extraction with oxygen, and washing method） on bleaching results in the activated acidic hydrogen peroxide bleaching with molybdate for eucalyptus kraft pulp is investigated． The results indicated that adding molybdate to the acidic hydrogen peroxide bleaching stage improved delignification degree and increased ISO brightness of bleached pulp（for example, with 0．1％ molybdate charge, delignification degree and pulp brightness could be increased 27．8％ and 4．3 points respectively）,but had little effect on the pulp viscosity．
