摘　　要：本文对蓝桉CTMP的H2 O2 单段置换漂白的影响因素 (H2 O2 浓度、漂液 pH值、漂白温度、漂白时间、Na2 SiO3及MgSO4 的使用浓度等 )进行了系统的研究 ,揭示了置换漂白的一般规律及较佳的漂白工艺条件。Single_stage displacement bleaching of E.globulus CTMP with hydrogen peroxide was investigated in this paper. The main parameters affecting bleaching such as H 2O 2 concentration, pH of the bleach liquor, temperature, bleaching time and the concentration of Na 2SiO 3 and MgSO 4 were studied. We also found the optimal conditions of displacement bleaching.
