| 摘 要： | 利用X射线光电子能谱（XPS）分析了竹浆粕在制备过程中其表面化学组成随漂白流程的变化。在漂白流程中除了漂白阶段以外，其它各段竹浆表面的O/C比值增加，表明除了漂白阶段以外木质素和抽提物在竹浆表面的浓度是降低的，表面木质素和抽提物含量的计算结果表明，漂白阶段竹浆O/C比的降低主要是由于抽提物从内部迁移到表面，当终漂浆粕进一步抽提，O/C比值接近纤维素的理论值。通过分析C1s峰C1～C4的相对含量得出，竹浆的主要化学成分随漂白流程的变化而变化，证明了木聚糖酶和DMD处理具有相同的效应，即有效地脱除了半纤维素和木质素。 |

| Abstract: | The change of surface chemical composition of bamboo pulp at bleaching stage during its preparation was analyzed with X-ray photoelectron spectroscopy(XPS).The ratio of O/C increased during bleaching process except bleaching stage,indicating the surface concentrations of lignin and extractive were reduced except bleaching stage.The calculation of lignin and extractive contents on the surface of bamboo pulp showed that the decrease of O/C in the stage of H2O2bleaching was primarily due to the transition of e... |
