Summary: | The invention relates to a plant fiber-based adsorbing material as well as a preparation method and application thereof. The plant fiber-based adsorption material is prepared by the following steps: carrying out substitution reaction on halogen on halogenated hydrocarbon with an epoxy group and hydroxyl on plant fiber to obtain modified plant fiber I introduced with the epoxy group; carrying out epoxy ring-opening and amine addition reaction on the epoxy group of the modified plant fiber I and the amino group of an amino compound with more than two amino groups to obtain an amino-introduced modified plant fiber II; and carrying out amidation reaction on the amino group on the modified plant fiber II and a carboxyl compound with more than two carboxyl groups or anhydride of the carboxyl compound to obtain a carboxyl-introduced plant fiber-based adsorption material III. The plant fiber-based adsorption material can be used for enriching rare earth elements in a low-concentration rare earth solution, has the adv |
