摘　　要：研究NaOH预处理对混合办公废纸酶法脱墨的影响。结果表明,与内切纤维素酶EGI脱墨相比,经NaOH预处理后再酶处理可提高油墨脱出率约10%。NaOH预处理的最佳工艺条件为:碱用量1.0%(对绝干浆),温度60℃,时间45min。The paper investigated the influence of NaOH pretreatment on the enzyme deinking of mixed office waste paper. The results show that the deinking rate of the waste paper pretreated with NaOH was increased by 10% than that with endoglucanase EGI deinking. The optimal technological condition for NaOH pretreatment is as follows: dosage of NaOH 1.0% ( absolute dry pulp), temperature 60℃, time 45min.
