桉木APMP制浆过程浆中残余木素分子量的变化

Variation of eucalyptus lignin molecular weight during APMP pulping

利用凝胶渗透色谱法和元素分析法测定了尾叶桉酶解木素在APMP制浆及漂白过程的分子量变化。研究结果表明：由于HOO-的特殊作用，制浆及漂白之后，浆中剩余木素的平均分子量相对有所增大。

GPC and element analyzer were used for detendnation of the number and weight average molecular weight of E. eucalyptus. The meults shows that during APMP pulping process, because of the special fimction of HOO-, the average molecular weight of cellulolytic enzyme ligmn increase relativey after APMP pulping and H2O2 bleaching.
