摘要
用木聚糖酶处理杨木APMP浆,除去浆中的部分半纤维素,通过紫外光谱与化学计量学软件相结合的方法检测酶解液中主要半纤维素组分的含量。同时对纸浆在酶处理前后的性能变化进行了测定,分析了不同的半纤维素溶出量对纸浆主要光学性能和物理性能的影响。
A part of hemicellulose was removed from poplar Alkaline Peroxide Mechanical Pulp （APMP） by xylanase treatment. The main hemicellulose components in the enzyme liquid was predicted with the model which was established by the spectral measurement of a set of hydrolyzed standard sugar solutions treating with concentrated sulfuric acid and a chemometrics software. The impact of dissolved hemicellulose content on APMP properties was analyzed through measuring the pulp optical and physical properties.
