Covalently Linked Poplar and Ayous Lignin-Based Hydrogels: Sustainable Materials for Water Remediation.

ABSTRACT: Lignin-based materials are attracting increasing attention for their effectiveness in treating polluted water. In this study, special emphasis is placed on hydrogels modified with lignin extracted from Poplar and Ayous (Alpi Spa wood waste) which were developed for the removal of organic dyes, using methylene blue as a model pollutant. The two types of wood differ notably in their characteristics. Poplar is a medium-density hardwood with a relatively low lignin content, higher water repellence, and good ability to be shaped and glued. Ayous is a tropical wood; its lignin has a different chemical makeup, offering greater resistance to microbial degradation. However, Ayous is more prone to moisture absorption and less durable outdoors if untreated. The lignins covalently incorporated into po
