摘　　要：本文研究了硫酸盐苇浆的臭氧漂白工艺,实验结果表明,室温下,采用35%浆浓,臭氧用量0.5%,反应时间3m in的条件,即能得到较好的漂白效果。选择了草酸作为臭氧漂的保护剂,并确定在浆浓10%,草酸用量0.2%,预处理30m in后,再进行臭氧漂白,说明了草酸对臭氧漂白具有较好的保护效果,可以增加臭氧漂白的效率和选择性。The conditions for reed kraft pulp bleaching with ozone were researched. The study showed that good bleaching results could be obtained at the conditions of room temperature, pulp consistency 35% , ozone charge 0.5% for 3min. Oxalic acid was selected as pretreatment agent before ozone bleaching, the pulp was treated with oxalic acid at dosage 0.2% , 10% pulp consistency for 30min. The result showed that oxalic acid can improve the efficiency and selectivity of ozone bleaching
