摘要
基于单线态氧机理的光化学漂白是一种新颖的环境友好漂白方法。使用自组装的光化学漂白装置,初步探讨了这种新型的漂白技术。利用TinoluxBBS和亚甲基兰(MB)作为光敏剂把氧气激发生成单线态氧进行纸浆的漂白。通过L9(34)的正交实验,研究了光化学漂白的主要影响因素,并且确定了TinoluxBBS和亚甲基兰(MB)作为光敏剂的优化漂白条件。同时也讨论了光敏剂对纸浆颜色的影响。
Photochemical bleaching of pulp based on singlet oxygen mechanism is a novel environmentally friendly bleaching method. The article investigated mainly photochemical bleaching of pulp based on singlet oxygen mechanism by using self--assembly device for photochemical bleaching. In the experiments, TinoluxBBS and methylene blue（MB） were used as photosensitizers to activate oxygen into singlet oxygen. According to orthogonal experiment of L9 （3^4）,the influence of primary factors on photochemical bleaching was determined and the optimum bleaching conditions of BBS and MB as photosensitizers were found. Influence on color of pulp by photosesitizers were also discussed.
