摘要：In this study, the synergistic effects of OBA and hydrogen peroxide on pulp brightness were investigated during the peroxide bleaching of a spruce TMP, and the bleaching chemicals cost were determined. The results show that the highest brightness was 75.45% ISO with conventional peroxide bleaching, while if a few of OBA was used with bleach liquors, the brightness could be raised to 85.98% ISO. The OBA brightening effect was remarkable at higher-brightness target. When it was 80 % ISO, the economic cost can be obtained with 0.6% OBA and 2.57 % peroxide.
