摘 要: 采用正交实验研究了玫瑰红用量、NaOH用量、反应时间和浆浓4因素对玫瑰红光催化单线态氧漂白硫酸盐蔗渣浆的影响,分别得出白度、高锰酸钾值、粘度和返黄值的最佳条件。 In this paper, RB photocatalysis singlet oxygen bleaching of bagasse kraft pulp was studied. In order to determine the optimum condition of the photochemical bleaching, the effects of some factors such as RB dosage, NaOH dosage, activation time and the pulp consistency were studied by orthogonal experiment. The results presented the optimum conditions for the bleached pulp with expected brightness, K value, viscosity, bleached pulp yield and reversion of brightness.
