竹沥液对粉单竹APMP浆木素返黄影响的研究

In this paper, the study proposed the effec of succus bambusae on bamboo lignin yellowing. It was based on the combined methods of UV and IR to analyze the lignin chromophore group after adding succus bambusae and UV-light irradiation. This would provide the evidence for the research of bamboo high-yield pulp yellowing. The result showed that the component of chromophore group on lignin increased after adding succus bambusae. Using UV-light irradiation, it would produced new chromophore grouop by lignin and the succus bambusae. Thus, this can cause brightness reversion, ans have obvious enhancement function to the yellowing of bamboo hiht-yield pulp.
