Abstract

This study aims to isolate nanocellulose from oil palm emptry fruit bunches (OPEFB) using acid hydrolysis method. Hydrolysis was carried out for 2 hours using 10% HCl and followed by centrifugation, ultrasonication and dialysis using a semipermeable membrane. The results obtained were tested by FT-IR, and it was found that there was a -OH functional group at a wavenumber between 3000-3500 cm-1, a C-H group in the area 2850-3000 cm-1, -CH2 bending at a wavenumber 1330-1465 cm-1 and the CO group at wave numbers 1000-1100 cm-1. This indicates that the product is in the form of cellulose. The particle size distribution of cellulose was tested with a PSA (Particle Size Analyzer) and the nanocellulose was about 7.2 nm in size.
从棕榈油空颗粒中分离纳米纤维素,使用酸性水解作为生物医学材料
采用酸水解法从油棕空果串(OPEFB)中分离纳米纤维素。用10%盐酸水解2小时,然后离心、超声和半透膜透析。利用FT-IR对所得结果进行了测试,发现在3000 ~ 3500 cm-1波数范围内存在一个-OH官能团,在2850 ~ 3000 cm-1范围内存在一个C-H基团,在1330 ~ 1465 cm-1波数范围内存在-CH2弯曲,在1000 ~ 1100 cm-1波数范围内存在CO基团。这表明该产品以纤维素的形式存在。用PSA(粒度分析仪)测定了纤维素的粒径分布,得到的纳米纤维素粒径约为7.2 nm。
