文摘内容 A series of Reed Pulps were prepared in which the level of Non-Process Elements (NPEs), including calcium, manganese, copper, iron were seclectively enriched and depleted, these pulps were then oxygen delignification,and the pulps were characterized according to kappa number, viscosity,brightness. The results indicated that the enrichment of NPEs have an important effulence on delignification,pulp viscosity and brightness, iron is the most harmful during oxygen delignification but manganese is just like a kind of aid and can enhance brightness and delignification。
