| Abstract: | By applying microwave radiation technique, hydrogen peroxide bleaching can change the structure of chromophoric groups of lignin, which accelerates bleaching rate and shortens bleaching time and effectively increases bleaching efficiency. The influence of power and radiation time of microwave and the amount of hydrogen peroxide on plant fiber are discussed. The proper conditions of microwave radiation bleaching are determined. The best bleaching result can be achieved when microwave radiation power is 800W, microwave radiation time is 1.5min, and the amount of hydrogen peroxide is 1.5% on dried pulp. |
| Keywords: | microwave radiation bleaching bleaching rate plant fiber |
