Abstract

Bamboo harvesting residues are wastes by-products of bamboo industries that contain holocellulose for about 63.14% to 70.71%, which often be discarded, incinerated or buried. In this study, carboxymethyl cellulose was prepared from bamboo harvesting residues (bamboo-branch and bamboo-tip) as raw materials. The chemical composition of bamboo harvesting residues, the viscosity and degree of substitution of carboxymethyl cellulose were determined. Carboxymethyl cellulose obtained was further characterized and compared by means of FTIR, SEM, XRD and TG. Results showed that under the optimized identical conditions, the viscosity and degree of substitution of carboxymethyl cellulose from bamboo-branch and bamboo-tip were 6.0 and 78.9 mPa·s, 0.75 and 0.89, respectively. Carboxymethyl cellulose obtained from bamboo-tip displayed a lower crystallinity and a better thermal stability as compared to synthetic carboxymethyl cellulose obtained from bamboo-branch and bamboo-culm.
