摘 要: 探讨了KMnO4对纸浆的漂白作用和活化作用。结果表明,KMnO4是一种良好的漂白剂和活化剂,具有替代O3漂白的可能性。O—Mn—P和O—Mn—Q—P漂序可将NaOHAQ麦草浆漂至80%ISO,从而彻底避免了氯化有机物的生成。 Potassium permanganate was investigated for the TCF bleaching of wheat straw pulp. It was found that potassium permanganate served very well as a bleaching and activating agent. Wheat straw soda AQ pulp was bleached to 80%ISO brightness in a bleaching sequence of OMnP or OMnQP.
