A review of the applications of organo-functionalized graphene nanocomposites for heavy metal adsorption

Abstract

Graphene is a promising material due to its unique mechanical, electrical, and thermal properties. chemical properties that are similar to those of graphite surface and can adsorb/desorb numerous atoms or Weakly attached adsorbates and NH۳,molecules such as OΗ, ΝΟΥ often behave as acceptors or donors, leading to fluctuations in the carrier concentration. This review discusses the applications of organo-functionalized graphene composites for the adsorption of heavy metals. The aspects reviewed include the commonly used organic materials for modifying graphene, the performance of the modified composites in heavy metals adsorption, effects of operational parameters adsorption .mechanisms and kinetic, as well as the stability of the adsorbents
