Abstract:

This paper reviewed the research progress in biomass⁃based materials used for iodine adsorption in recent years and introduced their classification in terms of their composition. Their synthesis methods， adsorption mechanisms， and adsorption effects were introduced， and their influence factors of iodine adsorption performance were summarized and evaluated， which included peak pyrolysis temperature， residence time， and activation methods. Moremover， the activation mechanisms of different activation methods for biomass⁃based materials in chemical activation methods were discussed. Finally， the future research directions of biomass⁃based materials in the field of iodine adsorption were presented based on a sustainable development concept.
