漂白

Amount of auxochrome phenolic hydroxyl(0.29 unit/C9)in lignin from H_2O_2 bleaching chemi-mechanical pulp is slightly higher than one of material(0.28 unit/C9), so amount of auxochrome phenolic hydroxyl can not be effectively decreased by alkaline peroxide bleaching process.

麦草化学机械浆纸浆经过碱性H_2O_2漂白，木质素中酚羟基含量(0.29个/C9)略高于原料中的酚羟基含量(0.28个/C9)，说明H_2O_2漂白不能有效地减少木质素中酚羟基这类助色基团的数量。
