This study investigated the possibility of enhancing the disruption of water hyacinth (WH) in an ultrasound-ionic liquid (US-IL) pretreatment assisted by sodium dodecyl sulfate (SDS). 1-butyl-3-methylimidazolium chloride ([BMIM]Cl) was used to dissolve the WH. The optimum concentration of SDS for the highest production of reducing sugar was also determined. Compared to the US-IL pretreatment, the production of reducing sugars, cellulose conversion and delignification were increased by 72.23%, 58.74% and 21.01%, respectively, upon addition of 0.5% SDS. Moreover, the enhancement of SDS in the US-IL pretreatment was confirmed by the analysis of structural features, which demonstrated that the SDS increased the removal of lignin and decreased the cellulose crystallinity.
本研究探讨了在十二烷基硫酸钠（SDS）辅助下，超声-离子液体（US-IL）预处理增强水葫芦（WH）破坏的可能性。[BMIM]Cl 用于溶解 WH。还确定了 SDS 的最佳浓度，以获得最高的还原糖产量。与 US-IL 预处理相比，添加 0.5% SDS 可分别将还原糖、纤维素转化率和木质素脱除率提高 72.23%、58.74%和 21.01%。此外，通过结构特征分析证实了 SDS 在 US-IL 预处理中的增强作用，表明 SDS 增加了木质素的去除，降低了纤维素的结晶度。
