摘　　要：用PhO2和SnO2为阳极材料、铁氰化钾为催化剂分别对纸浆进行电化学漂白,分析了不同电极 材料下漂后纸浆粘度、卡伯值和白度的变化,对2种电极材料下电化学漂白的选择性作了对比。研究表 明,Pb02作阳极时电化学漂白的选择性比SnO2好。Electrochemical bleaching using lead dioxide plate and stannum dioxide plate as anode, adding ferricyanide as catalyst, was carried out respectively. The change of viscosity, kappa number and brightness of the pulp was analyzed. The results showed that the selectively of electrochemical bleaching using PbO2 plate anode is better than that of using SnO2 plate anode.
