“…The presence of peaks at 463 to 560 cm -1 in RH is related to the Si-O-Si stretching in silica. Its disappearance in RH cellulose indicates that silica might have also been removed from RH (Shukla et al 2013).…”

“…RH is normally burnt as a crude source of energy (Munaf and Zein 1997;Jansen et al 2004), though it has also been used as bio-fertilizer, absorbent material, and pest control agent (Battegazzore et al 2014). This biomass source could be explored more extensively in view of its promising composition and advantageous features such as low density, renewability, and reasonable strength and stiffness (Shukla et al 2013).…”

The goal of this study was to pretreat rice husk (RH) using a microwaveassisted pretreatment process coupled with chlorite delignification and alkaline treatment to facilitate the isolation of cellulose. The isolated cellulose was characterized and subjected to structural analysis and a thermal stability test to ascertain the efficiency of the isolation from a visual perspective. The optimum condition for the microwave-assisted pretreatment of RH was determined by response surface methodology (RSM). The effects of three independent variables-microwave power, irradiation time, and solvent ratio-were investigated based on the maximum content of the RH being pretreated. At the optimum parameters of microwave power of 400 w, a 10-min duration, and a solvent ratio of 80.0% v/v, the pretreatment efficiency of RH was 10.0%. Compared with the conventional Soxhlet technique, the microwave pretreatment was superior. The X-ray powder diffraction (PXRD) result for the isolated cellulose showed that cellulose was highly crystalline (CrI = 65.0%). Fourier transform infrared spectroscopy (FT-IR) verified that most of the lignin and hemicelluloses were removed from the isolated cellulose after the chemical treatment. Furthermore, the TGA study revealed that the thermal stability of RH cellulose was higher than the original RH.

“…The size reduction and functionalization of cellulose further improves its properties for advanced applications like reinforcing and responsive agents. However, basic drawback of cellulose is processability and use of hazardous solvents for its extraction with less efficiency [6,7]. Thus, hybrid cellulose is prepared by grafting, blending and composite formation by using whisker, plasticizer and surfactants [8,9].…”

Extraction of chemically modified microcrystalline cellulose sheet (MCS) from rice husk is reported using a greener method. MCS is then blended with polyvinyl alcohol (PVA) by solution method under optimum conditions. The structural, morphological and physical properties were studied by spectroscopic, scanning electron microscope, gas chromatograph and standard ASTM methods. The result reveals the formation of carbonated microcrystalline cellulose blended polyvinyl alcohol (MCS-b-PVA) with improved mechanical, barrier and carbon di oxide releasing properties. Further, CO 2 releasing ability has made the film suitable for active packaging film for storage of meat products. The chemical mechanistic model for CO 2 release has been also proposed under the influence of hydronium ion and relative humidity in context of a close packet.

“…The high composition of organic carbon indicates that the is al lot of cellulose in the rice husk (Prabawati and Wijaya, 2008). The main component of rice husk is silica (15-17%) (Leiva et al, 2007;Stefani et al, 2005), other components are cellulose (35%), hemicellulose (25%), and lignin (20%) (Shukla et al, 2013). Due to its high cellulose content, rice husks can be used as a source of cellulose and can be used as a material that has benefits.…”

Abstract. Cellulose from rice husk has been successfully synthesized. Rice husk is an abundant agricultural waste and has a high cellulose content. Bioconversion of rice husk into cellulose begins with the stages of delignification and bleaching. The resulting cellulose was characterized using FTIR and XRD. The IR spectra show a strong absorption peak at 3444.87 cm− 1 which is associated with stretching vibrations O − H (hydrogen bonds between molecules), absorption peaks at 1033.85 cm− 1 are identified as stretching C − O − C which is β bond −1,4 glycosidic from cellulose. XRD shows the particle size of cellulose which is 3.44 nm and has crystallinity of 58.73%. These results indicate that cellulose from rice husk has good characteristics.
