摘要
设计了三因素三水平方案,讨论了制备成本低、高效、绿色环保纳米纤维素的最优因素。通过讨论不同的双氧水浓度、反应温度、辐照剂量对制备纳米纤维素的影响,得出最优工艺条件:过氧化氢浓度9%,反应温度为82.5℃,辐照剂量为120 kGy。此条件下,制备出纳米纤维素的聚合度为160.08,沉降量为38 mL,收率为75.46%。
A three-factor and three-level scheme is designed,and the optimal factors of nanocellulose for preparing low-cost,high-efficiency,green and environmentally are discussed.By discussing the effects of different hydrogen peroxide concentration,reaction temperature and irradiation dose on the preparation of nanocellulose,the optimal process conditions are obtained,the concentration of hydrogen peroxide is 9%,the reaction temperature is 82.5℃,and the irradiation dose is 120 kGy.Under the condi tions,the degree of polymerization of nanocellulose is 160.8,the settling volume is 38 mL,the yield is 75.46%.
