玉米秸秆和撑篙竹乙醇精炼废液制备木质素纳米颗粒的研究
Direct Preparation of Lignin Nanoparticles from Ethanol Refining Waste Liquor of Corn Straw and Bambusa Pervariabilis
摘要
Abstract
This study utilized ethanol refining waste liquor of corn straw and Bambusa pervariabilis to directly prepare lignin nanoparticles(LNPs)with good stability and uniform size with ultrasonic-assisted.By adjusting the pH value,adding surfactant dosage,and ultrasonic time,the process parameters were optimized adopting the response surface method.The results showed that the ultrasonic time primarily af-fected the micro-morphology and distribution uniformity of LNPs.Using cetyltrimethylammonium bromide(CTAB)as a surfactant,under op-timized process conditions,LNPs directly prepared from corn straw ethanol refining wastewater had a particle size of 257.1 nm,while that prepared from Bambusa pervariabilis ethanol refining wastewater was 183.0 nm.Similarly,using sodium dodecyl sulfate(SDS)as a surfac-tant,under optimal process conditions,the LNPs directly prepared from Bambusa pervariabilis ethanol refining wastewater had a particle size of 195.2 nm and showed better dispersion stability in water with retention rate of＞60％after allowing the LNPs dispersion to stand for 7 days.The LNPs obtained by various methods all exhibited good thermal stability at＜200℃.关键词
