Abstract

In the present study, Chickpea (Cicer arietinum L.) stems are used for the extraction of cellulose and successfully applied for handmade paper making. The obtained cellulose characterized using chemical analysis, Fourier transforms infrared spectroscopy (FTIR), X-ray diffraction (XRD), Differential scanning calorimetry (DSC), and Scanning electron microscopy (SEM). Chemical analysis evidenced that treated chickpea stem has 49.23% cellulose content. The FTIR analysis revealed changes in functional groups indicate removal of non-cellulosic constituents. The XRD analysis evidenced that extracted cellulose has a 53% crystallinity index. DSC studies demonstrate extracted cellulose stand at higher thermal degradation temperatures from 337 oC to 368 oC. The morphology of the extracted cellulose showed a coarse and fibrous surface. The physical properties of the hand made paper produced from chickpea cellulose pulp indicate the suitability of chickpea stem cellulose as an alternative non-wood source for the pulp and paper industry.
