摘要：
The objective of this work was to determine optimum conditions for oxygen bleaching of kraft wheat straw cellulose using designed experiments and statistical techniques. The three process variables for the delignification of kraft pulps examined were time of delignification, added alkali concentration, and remaining alkali concentration. There was good fit between calculated and experimental vales for bleached pulp yields using polynomial models. There are optimum processing conditions of oxygen bleaching to produce suitable wheat straw cellulose.
