Lignin is one of the most abundant and significant natural polymeric materials in the world, and its position is only second to cellulose. In woody plants, lignin content accounts for about 25%. Due to its chemical inertness and structural complexity, the application of lignin is very limited. Therefore, the chemical modification of lignin is the key method to transform lignin into functional materials, which is of great significance for the sustainable development of resources and environment. In this review, the research progress on the development of chemical modification of lignin and its applications, including wastewater treatment, heterogeneous catalysis and other aspects, are summarized. Furthermore, discussions on challenges and perspectives in the field of lignin modification are also presented.

Key words: Lignin, Chemical modification, Sewage treatment, Heterogeneous catalysis, Flame retardant
