Fig. 5From: Modification of pomegranate waste with iron ions a green composite for removal of Pb from aqueous solution: equilibrium, thermodynamic and kinetic studiesThe effect of composite dose on adsorption capacity. The change of adsorption capacity in removal of the Pb2+ vs amount of adsorbents in solution for Fe2+-PPC is depicted in red and for Fe3+-PPC is depicted in blueBack to article page
