摘　　要：采用由Cu-salen、吡啶、H2O2、O2组成的Cu-salen型仿酶体系进行了针叶木CTMP浆的漂白研究,并探讨了Cu-salen、NaOH、反应温度,反应时间等对预处理和漂白后纸浆白度的影响。研究结果表明,Cu-salen型仿酶系统对针叶木CTMP浆预处理有较好的效果。Cu-salen system comprised of Cu-salen, pyridine, hydrogen peroxide, oxygen was used to investigate the bleaching of softwood CTMP pulp. The effect of Cu-salen dosage, NaOH dosage, reaction temperature and reaction time on brightness of the pulp before pretreatment and after bleaching was probed. The findings indicate that the Cusalen biomimetic system has a desirable effect on the pretreatment of softwood CTMP.
