Abstract
It has been proposed to test the microcrystalline of cellulose materials using polarized light microscope (PLM) and uv-visible spectrometer . The microcrystalline cellulose was prepared from kenaf bast fibers while the nano crystalline was prepared from alpha cellulose using thermal acid hydrolysis. We use at 20% (v/v) and 40% (v/v)H2 SO4 in the experiment mixed and stirred within an hour up to hours. The testing using PLM clearly indicates the existence of microcryatalline cellulose while the use of uv-visible spectrometer can reveal the effectiveness of the acid hydrolysis in extracting the nanofibril from the alpha cellulose.
