Thermally Stable Rice Husk Microcrystalline Cellulose as Adsorbent in PTLC Plates

Abstract

Microcrystalline cellulose (MCC) was prepared from rice husk by subjecting it to alkalinepretreatment, delignification, bleaching, and hydrolytic operations. MCC was also prepared from cotton wooland used as a reference because of its high cellulose content to estimate a relative yield and quality of theMCC produced from rice husk. The characteristic morphological feature was established by scanning electronmicrograph (SEM) and the crystallinity of the Rice husk Microcystalline cellulose was further confirmed usingthe X-RD technique; the functional group was confirmed by the Fourier transform infrared (FTIR) spectroscopicmethod 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 thethermal stability was determined from thermogravimetric analysis (TGA). The characterized MCC of rice huskwas applied as a stationary phase in Preparative Thin Layer Chromatography gave good separation (PTLC).
