As a major component of lignocellulosic biomass, lignin has lots of fascinating properties, which make them become interesting natural polymer raw material. Here, the lignin isolation, modification strategies, polymerization method and process, and the promising applications were summarized and analyzed in recent years. Specially, the preparation of high excellent adsorbents from deconstructed lignin products are highlighted from the synthesis methods and adsorption mechanism perspective. Abstract As a major component of lignocellulosic biomass...
