Thermally stable rice husk microcrystalline cellulose as adsorbent in PTLC plates

Abstract

Microcrystalline cellulose (MCC) was prepared from rice husk by subjecting it to alkaline pretreatment, delignification, bleaching, and hydrolytic operations. MCC was also prepared from cotton wool and used as a reference because of its high cellulose content to estimate a relative yield and quality of the MCC produced from rice husk. The characteristic morphological feature was established by scanning electron micrograph (SEM) and the crystallinity of the Rice husk Microcystalline cellulose was further confirmed using the X-RD technique; the functional group was confirmed by the Fourier transform infrared (FTIR) spectroscopic method with characteristic absorption bands of;–OH stretching at 3416 cm-1; C-H stretching at 2918 cm-1;-OH bending at1377 cm-1;, 1159 cm-1; and C-O-C pyranose ring skeletal vibrations at 1026-1033 cm-1, and the thermal stability was determined from thermogravimetric analysis (TGA). The characterized MCC of rice husk was applied as a stationary phase in Preparative Thin Layer Chromatography gave good separation (PTLC).
