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.
