| Abstract:This paper investigated the effect of seven factors (bleaching agent, alkali dosage, bleaching temperature, etc) on mulberry stalk SCMP hydrogen peroxide bleaching through single factor experiment, and evaluated the significances of these seven factors with Plackett-Burman in MODDE. The most significant factors obtained were reaction temperature, time and the amount of hydrogen peroxide. The three main factors and their respective four levels were carried out. The experiment designed and analyzed based on by RSM in MODDE. Finally the optimal bleaching process was obtained as follows: reaction temperature 90℃, reaction time 104 min, pulp consistancy 15%, the alkali ratio and the dosages of H2O2, Na2SiO3, MgSO4 were 0.7, 8%, 0.3% and 0.10%, respectively. |
