Abstract

This work proposed a facile method to prepare lignin nanosphere antioxidants by self-assembly for the valorization of biomass lignin waste. The technical feasibility of four biomass lignin extractions with choline chloride–lactic acid deep eutectic solvents (DESs) was comparatively assessed. Results showed that the lignin fractionation with DES pretreatment was effective, and the lignin yield reached up to 18.4%. The average particle size of the obtained lignin nanospheres (LNPs) was in the range of 20 ∼ 80 nm at pH = 7. It was proposed that LNPs prepared from deep eutectic solvent technical lignin could be used as promising biodegradable nanoantioxidants with comparable antioxidant ability to natural phenolic compounds. The large number of phenolic hydroxyl groups exposed on the LNP surface benefited its antioxidation performance. This work showed a facile way to prepare lignin nanoantioxidants with DES technical lignin and also provided useful chemical information on the correlation between lignin phenolic hydroxyl groups and its antioxidation ability.

木质素纳米抗氧化剂制备木质素生物质废弃物的研究
本文提出了一种自组装制备木质素纳米球抗氧化剂的简便方法,用于生物质木质素废物的增值。比较评价了氯胆碱-乳酸深度共熔溶剂(DESs)萃取四种生物质木质素的技术可行性。结果表明,采用DES预处理对木质素进行分馏是有效的,木质素得率可达18.4%。在pH = 7时,得到的木质素纳米球的平均粒径为20 ~ 80 nm。提出了由深度共晶溶剂技术木质素制备的LNPs具有与天然酚类化合物相当的抗氧化能力,是一种很有前途的生物可降解纳米抗氧化剂。大量的酚羟基暴露在LNP表面,有利于其抗氧化性能。本研究为利用DES技术制备木质素纳米抗氧化剂提供了一种简便的方法,并为木质素酚羟基与其抗氧化能力的相关性提供了有用的化学信息。
