| Abstract:The present study optimized the performic acid extraction of cellulose from bamboo by the combined use of single factor method and response surface method （RSM）. In the extraction process, bamboo was oxidized with performic acid at a certain temperature for the removal of hemicelluloses and lignin. The influences of performic acid concentration, extraction temperature, reaction time, as well as interactions of each two of above three variables on the response values （i.e., cellulose content extracted） were investigated. The results indicated that the cellulose content of extracted was affected in decreasing order by the following factors: reaction time>extraction temperature>performic acid concentration. Through response surface method, the process conditions for cellulose extraction were optimized as follows: temperature 35.78℃, reaction time 19.93 h and performic acid concentration 0.45 mol/L. Under these conditions, the yield of cellulose extracted from bamboo was 95.1%. |
