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。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.
