Research Progress of Adsorbents based on Collagen Fibers
Adsorption operation plays a crucial role in the chemistry and chemical engineering.Developing environmentally friendly,cost-effective,and efficient adsorption materials is of great significance for the future development of adsorption technology.Collagen fibers(CFs),a kind of natural biomass resource mainly derived from animal skins,possess a unique three-dimensional hierarchical structure and abundant active functional groups,which suggesting their considerable research value and boundless potential for the production of superior adsorbents.This review provides an overview of the advancements in the development of CFs-based adsorbents,specifically focusing on CFs immobilized by tannin,CFs loaded with metal ions,and CFs grafted with functional groups.The application of these adsorbents in the removal of radionuclide ions,toxic heavy metal ions,inorganic anions,organic contaminants,as well as in the separation of natural products and the immobilization of cells are discussed.Additionally,potential areas for future research and development of CFs-based adsorbents are also prospected.
