Cinnamon wood as an adsorbant for the removal of Cu2+ from aqueous solutions

Abstract

Heavy metal water pollution remains one of the most harmful ecological and health issues globally, and Cu2+ is a common pollutant found in water bodies. Cinnamon (Cinnamomum verum or Cinnamomum zeylanicum) is native to Sri Lanka. Cinnamon wood is discarded as firewood, making it an ideal candidate as a locally available low cost adsorbent for Cu2+.
