Ultrasound-assisted acid hydrolysis preparation technological conditions of bamboo pulp nano-cellulose were optimized by response surface methodology. The results showed that optimization of nano-cellulose preparation technological conditions was 22 min of ultrasound time, 49.46℃ of reaction temperature and 3.25 h of reaction time. Under optimization, nano-cellulose average yield was 49.92 %, which was closed to 50.08 % of response surface methodology predicted values. The influencing factors of nano-cellulose yield are followed by reaction time, ultrasound time and reaction temperature.
