摘　　要：在碱性麦草浆过氧化氢漂白过程中,利用微波加热,可以大大提高反应速率,加快漂白进程。传统方法漂白需1～2h,利用微波加热只需1～2min即可达到甚至超过传统漂白所达到的结果。另外,酰胺助剂TAED对H2O2漂白具有明显的改善效果,TAED活化的H2O2漂白与单纯的H2O2漂白相比,具有漂白时间短、漂浆白度高等优点。Oxidize hydrogen bleaching the alkaline wheat straw pulp that is heated with microwave is of benefit to seed up the bleaching progress. The traditional means needs 1-2h, but if the pulp heated by microwave, only needs 1-2min to reach the effect of traditional means. Besides, TAED adjust H2O2 have obvious improvement effect, and TAED adjust H2O2 bleaches against pure H2O2 to bleach, has the strong point of bleaching time shorter, bleaching degree higher.
