| 中文摘要: |
| 从粉单竹中提取竹沥液，探讨了竹沥液对粉单竹磨木木素、粉单竹未漂及漂后APMP磨木木素发色基团的影响，并采用紫外光谱和红外光谱分析木素发色基团的变化。结果表明，竹沥液中含有发色基团，且竹沥液会吸附在木素上，从而增加木素共轭羰基的含量；经紫外光照射后，木素及吸附在其表面的竹沥液会生成新的发色基团，进而影响粉单竹APMP的白度和返黄程度。 |
| Abstract: |
| This thesis mainly discussed the influence of succus bambusae on bamboo lignin’s chromophore groups during Bambusa Chungii APMP yellowing. The succus bambusae extracted from bamboo was added to APMP’s lignin. And the mixture suffered from UV-light radiation. The change of their chromophore groups was determined by UV and IR spectrometry. The result showed that the component of conjugated groups of the lignin increased after adding succus bambusae. After UV-light radiation, new chromophore groups were produced in lignin and succus bambusae, this influenced the bleaching and yellowing of bamboo APMP significantly |
