中文摘要：

采用由Co—salen、吡啶、H2O2、O2组成的Co—salen型仿酶体系进行了针叶木CTMP浆的漂白研究．并讨论了漂白过程中纸浆卡伯值、白度和黏度的变化规律。结果表明，Co—salen仿酶漂白在溶出木素大分子方面能力并不强．主要通过将木素氧化为含羰基的产物，使其在后续碱抽提和H2O2漂白中容易降解或溶出。

英文摘要：

Unbleached softwood kraft pulp was treated with a biomimetic bleaching system, i.e. Co-salen system comprised of Co （ Ⅱ ）salen, pyridine, hydrogen peroxide, oxygen （Co-salen system） and the changes of kappa number, brightness of the pulp after biomimetic treatment were analyzed. It was found that Co-salen system had a limited ability to decrease kappa number and increase brightness. The result illustrated that the Co-salen system was not effective in lignin macromolecule. However, biomimetc process oxidized a part of lignin to be carbonyl compounds which was easy to be degraded and dissolved during alkali extraction and hydrogen peroxide bleaching. Consequently, this work provides a convictive information about Co-salen biomimetic delignification system that could be applied to industrial bleaching.
