| 摘 要： | 为探讨表面活性剂对超声波-离子液体(US-IL)预处理木质纤维素的影响,本试验采用十二烷基硫酸钠(SDS)强化US-IL对水葫芦进行预处理,通过酶解、组成成分、表面形貌、结晶度以及化学结构的变化对预处理效果进行考察.结果显示,与未添加SDS相比,超声波-离子液体-十二烷基硫酸钠(US-IL-SDS)预处理能够有效降低纤维素的结晶度并去除木质素,酶解还原糖产量、纤维转化率及其脱木率分别提高72.23%、58.74%及21.01%.并且,SEM、XRD以及FTIR结果也表明SDS能够促进US-IL对水葫芦结构的破坏.因此,将SDS运用于辅助US-IL预处理木质纤维素具有一定可行性和良好的运用前景.

| Abstract: | This study investigated the effects of surfactant (sodium dodecyl sulfate, SDS) in the lignocellulose pretreatment process with ultrasound-ionic liquid (US-IL) on the enzymatic hydrolysis efficiency, and the composition, morphology, crystalline and chemical structure of water hyacinth. The results show that the crystalline of cellulose and the lignin in biomass were cracked and removed effectively. Meanwhile, the production of reducing sugars, cellulose conversion and delignification increased by 72.23%, 58.74% and 21.01%, respectively. Moreover, SEM, XRD and FTIR analysis also demonstrate that the structure of the water hyacinth was destroyed by the ultrasound-ionic liquid-sodium dodecyl sulfate (US-IL-SDS) pretreatment. Overall, the novel pretreatment process with ultrasound-ionic liquid and surfactant had a great potential in lignocellulose disposal and reutilization. |
