Study on the Pretreating Approaches for the Potato Straws
Ningxia Normal University, Guyuan, Ningxia, China
This paper proposes an approach to pretreat the potato straws. Specifically, potato straws are handled using various kinds of chemical solutions, including HCI, H2SO4, NaOH and NaOH+H2O2, under different concentrations. For each kind of solution, particular indicators, such as the cellulose content as well as scarification ratio of the treated straws, are studied in the paper. Based on orthogonal experiments, the best pretreatment effect is obtained by using the solution of 4% NaOH under temperature of 60º Celsius, solid-to-liquid ratio of 1:10, and processing time of 6d.
