摘    要:进行亚硫酸镁盐竹子/蔗渣浆的酸性H2O2漂白。结果表明,在实验条件下,H2SO4及EDTA的预处理能显著降低浆中过渡金属离子的含量,改善酸性H2O2漂白效果;在漂白过程中,添加适量的柠檬酸,对提高漂浆白度、粘度等有好处。

关 键 词:金属离子  酸性过氧代化氢漂白  亚硫酸镁盐浆  预处理

Abstract:Pretreatments before acidic hydrogen peroxide bleaching of magnesium based sulfite bamboo/bagasse pulp with sulfuric acid(A)or EDTA(Q)were conducted.The acidic hydrogen peroxide bleaching with the addition of citric acid were done.The results show that A or Q pretreatment can obviously decrease the contents of transition metal ions in the pulp and improve the bleaching response.During the acidic hydrogen peroxide bleaching,the addition of citric acid gains good results in increasing the brightness and viscosity etc.
Keywords:magnesium  based sulfite pulp  metal ions  pretreatment  citric acid  acidic hydrogen peroxide bleaching
