The invention provides a method for preparing lignin nanotubes by using agricultural and forestry biomass raw materials. The crushed biomass raw materials are dispersed in an inorganic alkaline solution, a cosolvent is added to it, ball milling is performed, and then the supernatant is collected by centrifugation; Inorganic acid was added dropwise to the supernatant until the solution became neutral, and then dialyzed using a semipermeable membrane to obtain a solution containing lignin nanotubes. The method can effectively solve the problems of complex operation process and environmental pollution existing in the existing methods. |
