化学热磨机械浆漆酶改性工艺研究

The Technical Study on Chemithermomechanical Pulp Modified by Rhus Vernificera Laccase

通过对马尾松化学热磨机械浆进行漆酶改性处理的工艺条件研究,探讨了漆酶用量、体系pH、介体用量、酶处理时间、酶处理温度等因素对改性效果的影响,得出漆酶改性的较佳工艺条件为:漆酶用量2.0 U/g,ABTS用量0.5%,体系pH 6,酶处理温度50℃,酶处理时间1 h。

The masson pine chemithermomechanical pulp（CTMP） was treated with laccase,and various impacting factors were investigated such as： the charge of laccase,pH,temperature.It was found that the optimum conditions were： the charge of laccase 2.0 U/g pulp,ABTS 0.5% pulp,pH 6,temperature 50 ℃,reaction time 1 h.
