Abstract:Lignin with rich functional groups and high mechanical strength has been employed for the capture of different pollutants under complex environmental conditions. The capture performance can be further improved by chemical modifications such as grafting, cross-linking, and copolymerization. Herein, highpurity lignin was first extracted from xylitol residue using a strategy of ionic liquid extraction followed by acid hydrolysis. Then the prepared macrocyclic compounds, such as crown ethers and columnar aromatics… Show more
