| Abstract: | In recent years, the high-value utilization of lignin and its derivatives have received widespread attention. Sulfonated lignin (SL) is an important functional lignin derivative derived from the sulfonation modification of natural or industrial lignin, which has a wide range of applications in several fields. The structural differences of SL directly determine its characteristics, thereby affecting its performance. Based on analyzing the main structure and physicochemical properties of SL, this article summarizes its main application areas, and focuses on different modification strategies in functional application fields such as adsorbents, dispersants, flocculants, and water-reducing agents. Meanwhile, it reviews the role of Density Functional Theory calculations in investigating the mechanisms of structural modification and performance enhancement of SL. Finally, in view of the current limitations in structural regulation of SL, some new strategies are proposed to achieve precise optimization of its performance. (Copyright © 2026 Elsevier B.V.
