The presence of organic dyes in the aquatic environment is aserious global problem because of the serious negativeconsequences on the quality of ecosystems. Among various physico-chemical methods, the adsorption could be con-sidered a promising alternative for removing dyes from aqueous media, due to its efficiency, high selectivity, lowcost, ease of operation, simplicity, and availability in a wide range of experimental conditions. However, all these ad-vantages are closely related to the nature of adsorbent material used in the adsorption processes of dyes. The adsor-bent materials available in large quantities requiring a simple preparation will enhance the benefits of theadsorption processes, in agreement with the concepts of green chemistry. This review is focused on the use ofleaf-based materials, in raw or modified forms, as adsorbents for the removal of dyes from aqueous effluents,with applications in the wastewater treatment. This review addresses characterization of leaf-based adsorbents,possible utilization of leaf-based adsorbents (raw and activated forms) for dye removal and possible applicationsin pilot and full scale systems. Also, thermodynamics, equilibrium and kinetic parameters of dye adsorption onleaf-based adsorbents are discussed. The practical utility of leaf-based adsorbents for dye removal, and their possibleuses in the treatment of industrial wastewater are copiously highlighted.
