| Abstract: |
| This paper reviewed the research progress of lignin modified materials in the adsorption and removal of dyes from water. Firstly， the structure of lignin was analyzed， and the adsorption performance of modified lignin was analyzed with a focus on different types of dyes （methylene blue， Congo red， malachite green）.By discussing the structure-effect relationship between adsorption properties and lignin modification methods （phenolic modification， sulfonation treatment and graft copolymerization）， this paper revealed the advantages of modified lignin in improving the adsorption capacity， increasing the selectivity， and facilitating the regeneration of the adsorbent， and offered a prospect for the future direction of the development of lignin-based adsorbent materials. |
