摘要:对经碱性H2O2漂白以及NaBH4还原处理后麦草化学机械浆的木质素结构进行了分析研究。结果表明,麦草化学机械浆经碱性H2O2漂白后总羰基含量减少了26.4%,后续NaBH4还原处理后木质素中共轭羰基数量又减少了70.0%,漂白破坏了木质素中的发色基团。
Lignin structures in wheat straw materials,its chemi-mechanical pulps,the pulps bleached with alkaline H2O2 and the pulps treated by H2O2/NaBH4 were determined in this paper.The results showed that conjugated carbonyl content in the lignin of H2O2 bleached chemi-mechanical pulp decreases by 26.4%,conjugated carbonyl in the lignin of the pulp treated by NaBH4 further decreases by 70.0%.The chromophore in the lignin is broken by bleaching,which improves the pulp brightness.
