Eucalyptus-based Materials As Adsorbents for Heavy Metals and Dyes Removal from (Waste)waters

Eucalyptus is the most widely planted type of hardwood trees. It considers as a cheap, renewable, and ecofriendly biomass source for the production of high value materials. In this context, Eucalyptus-based adsorbents in raw, modified, and carbonaceous forms have been efficiently applied to remove a variety of toxic and carcinogenic aquatic pollutants. This article provides a comprehensive review on the application of Eucalyptus-based adsorbents for the removal of heavy metal and dye pollutants from waste(water). The use of Eucalyptus residues such as bark, leaves, wood or sawdust, and seeds to prepare adsorbents is considered. The performance of Eucalyptus-based adsorbents towards the tested pollutants, as well as their reuse after regeneration is discussed. Furthermore, the adsorption isotherms, kinetics, thermodynamics, and mechanisms are also considered. Finally, the findings and future prospects for the Eucalyptus-based materials and their use as adsorbents for water treatment are presented. (c) 2022 Elsevier B.V. All rights reserved.
