Abstract
In this work,corn straw was pretreated by dilute acid method,reducing sugar in the hydrolysate was measured by DNS method.After analysis on hydrolysis temperature,hydrolysis time,sulfuric acid concentration and solid-to-liquid ratio separately,the optimized hydrolysis conditions were obtained by orthogonal experiments:corn straw was treated with 0.6% sulfuric acid at 121 ℃ for 1h,and solid-to-liquid ratio is 10%.
