| 摘 要： | 系统研究了旧报纸碎浆过程中释放的溶解与胶体物质(DCS)。利用气相色谱-质谱联用技术(GC-MS)分析了在碎浆过程中产生的碳水化合物、树脂酸和脂肪酸,并用紫外分光光度法定性定量测定了木素含量。结果表明,DCS中溶解性物质占较大比例,碎解过程中释放出最多的糖类是木聚糖,而亲脂性抽出物中树脂酸的含量高于脂肪酸的含量,DCS中的木素主要以溶解木素的形式存在。

| Abstract: | The dissolved and the colloidal substances(DCS) released during the pulping of the old newspapers were studied systematically.The carbohydrates,the resin acids and fatty acids were analyzed by using GC-MS and the lignin content was determined qualitatively and quantitatively by UV-spectrophotometer.The results showed that carbohydrates account for a large proportion of the DCS,and the content of resin acids is higher than that of fatty acids in the lipophilic extractives while the lignin represents mainly in the dissolved ones. |
