摘要
研究了用EDTA和CaSO4 作为螯合剂预处理马尾松硫酸盐浆前后非过程元素含量的变化 ,探讨了非过程元素在氧漂中对木素脱除率和纸浆粘度的影响 ,结果表明非过程元素对脱木素的选择性有很大影响 。
Oxygen bleaching is the trend of non-polluting bleaching.Alalyze the importance of demoval of NPEs in KP wood pulp by the chelation of EDTA and CaSO 4. The influence of NPEs on delgninfication rate and viscosity of pulp during oxygen deligningfication ,the influence Of NPEs on the selectivity of deligninfication are studied,pointing out the key role of the accumulation of element of Ca.
