摘　　要：对硫酸盐法竹浆次氯酸盐-二氧化氯(HD)漂白工艺进行了研究。结果表明,竹浆HD短序漂白工艺优于传统的CEH漂白工艺。并进一步研究了在ClO2漂白过程中加入少量的杂多酸,可以提高纸浆白度或在保持纸浆一定白度的情况下减少ClO2漂剂的用量。In this paper, bleaching of kraft bamboo pulp with HD short sequence was studied. Resuhs indicated the HD bleaching was superior to the conventional CEH bleaching for kraft bamboo pulp, the HD bleaching wholly substituted for the conventional CEH bleaching. In addition, a few hetcropoly acid added to ClO2 bleaching are studied, results indicated, the brightness of the bleached bamboo pulp increased or the ClO2 dosage was decreased and the brightness of the bleached bamboo pulp steadied.
