Abstract:
The widespread contamination of aquatic systems by persistent organic pollutants, such as pharmaceuticals, dyes, and industrial chemicals, presents a significant environmental threat due to their potential for bioaccumulation and detrimental effects on ecosystems. Lignin, a widely available biopolymer with polyphenolic structures, has gained recognition as a promising adsorbent due to its renewability, structural flexibility, and cost-effectiveness. This review systematically examines recent advancements in lignin-based advanced materials for the remediation of organic pollutants in aqueous environments. It focuses on key strategies to enhance adsorption performance, including physical and chemical modifications, as well as structural engineering. Special attention is given to understanding the structure-performance relationship by analyzing interactions between pollutants and lignin. It also aims to provide valuable insights into the design of next-generation lignin-based adsorbents while addressing existing challenges and opportunities for real-world application.
