Optimization of extracting cellulose from sugarcane bagasse using ultrasound-assisted alkaline hydrogen peroxide
摘要
Abstract
[Objective]The effect of ultrasonic on the extraction process and the cellulose content was studied to optimize the process of extracting cellulose from sugarcane bagasse.[Method]The best parameters of extracting cellulose from sugarcane bagasse using ultrasound-assisted alkaline hydrogen peroxide were determined,and the influence of ultrasonic treatment on the morphological structure of bagasse cellulose was also researched using inverted microscope.[Result]Under the optimum conditions (ultrasonic intensity of 200W,extracting time of 70 min,extracting temperature of 80℃,the mixed solution H2O2 and NaOH concentration of 0.7% and 6%),the content of bagasse cellulose reached more than 87.54%,which increased by 8.69% compared with no auxiliary of ultrasonic.[Conclusion]Using ultrasound-assisted alkaline hydrogen peroxide to pretreat bagasse,the reagent of accessibility and reaction performance of bagasse fiber were improved.The reaction time was reduced,and the reaction efficiency was boosted.关键词
