Extraction and Characterization of Cellulose Nanocrystal from Palm Leaves(Trachycarpus Fortunei)
摘要
Abstract
In this study,palm leaves were utilized as raw materials to prepare cellulose nanocrystal(CNC)through a combination of chemical treatment and acid hydrolysis,followed by analysis and characterization.Firstly,cellulose fibers were extracted from palm leaves via sodium chlorite treatment and alkaline treatment.Subsequently,the extracted cellulose fibers were hydrolyzed using concentrated sulfuric acid to pro-duce CNC.The microscopic morphology and chemical composition of the palm leaf fibers were characterized using Fourier transform infrared spectroscopy(FT-IR),X-ray diffraction(XRD),thermogravimetric analysis(TG),scanning electron microscopy(SEM),and transmission elec-tron microscopy(TEM).The results showed that non-cellulosic components(lignin and hemicellulose)in the palm leaves were successfully re-moved through chemical treatment.After acid hydrolysis,rod-shaped CNC were successfully isolated.The yield of cellulose fibers from palm leaves reached 23.1%.The extracted CNC exhibited a crystallinity of 75%and an average aspect ratio of 18.关键词
