马铃薯渣纤维素的纯化及纳纤化
Purification and Nano-fibrillation of Cellulose from Potato Residue
摘要
Abstract
Chemical,biological and bio-chemical methods were adopted to purify the cellulose from potato residue,and then the cellulose was bleached with H2O2. At last,the purified cellulose was treated with high pressure homogenizer in order to obtain the nano-fibrillated cellulose(NFC). The morphology of the cellulose from potato residue was characterized with optical microscopy,SEM and Laser particle size analyzer,and the crystallization properties were determined with X-ray diffraction(XRD). The results showed that the order from high to low of the yields with different methods is as follows:biological method,bio-chemical method and chemical method. The brightness of the cellulose inceased significantly from 22.6%ISO to 84.0%ISO. All the samples before homogenization had the similar sheet structure,while it changed into mi-crofibril structure with the width less than 100,nm after homogenization. The cellulose from potato residue has the same crys-talline structure,namely Cellulose I. The homogenization with high pressure can somewhat damage the structure of the cellu-lose crystals,which leads to a decrease of the crystallinity.关键词
