摘　　要：研究了脱墨浆过氧化氢漂白特性。研究结果表明 ,脱墨浆采用过氧化氢漂白时 ,过氧化氢的无效分解的程度大。脱墨浆采用过氧化氢漂白时 ,过氧化氢同氢氧化钠用量比为 1∶0 .6,漂白反应时间为 2h ,漂白反应温度为 70℃ ,浆浓为 1 0Hydrogen peroxide's bleaching characteristics of deinked pulp was studied in the paper . It was shown that the reason why most of hydrogen peroxide separated ineffectively in the course of deinked pulp's hydrogen peroxide bleaching was uncertain.The deinked pulp could be bleached to higher brightness under the following condition: the ratio of the charge of hydrogen peroxide to that of sodium hydroxide :1∶0.6, bleaching time : 2 h, bleaching temperature : 70℃, pulp consistency: 10%.
