Abstract

This study sought to examine the removal of some heavy metal ions from an aqueous media utilizing an adsorbent made from waste materials Cyperus papyrus and nano Cyperus papyrus. Because of their abundance of (OH) groups, Cyperus papyrus biomaterials are promising adsorbents for removing heavy metals. Therefore, this study proposed removing Al, Fe, Pb, and Cd from aqueous solutions using dried Cyperus papyrus. The effectiveness of removal was determined to be in this sequence Fe >Pb> Cd>Al. In another method, some of the cyperus papyrus was converted to nanopowder and used to investigate the elimination of Pb and Cd from aqueous solutions, and the results showed that the nano cyperus papyrus is more effective than normal cyperus papyrus. Normal cyperus papyrus was applied into two samples; the first was a sewage water sample, and the other was ground water. The Freundlich isothermal adsorption method worked better for the adsorption of Al, Fe, Pb, and Cd using Cyperus papyrus, and it also demonstrated an ion exchange process that took place in the adsorption surface layer that is uneven. Cyperus papyrus had a high affinity for adsorbing heavy metals Al, Fe, Pb, and Cd without additional chemicals. The results revealed that the used adsorbent had been a promising material for treating some contaminants and was eco-friendly.
