Modification of pomegranate waste with iron ions a green composite for removal of Pb from aqueous solution: equilibrium, thermodynamic and kinetic studies

SEM images of adsorbents prepared for adsorption of Pb. SEMs were recorded in the acceleration voltage 15.00 kV and magnitude ×100.00 for focusing on surface porous. a SEM image of pomegranate peel carbon and b iron modified pomegranate peel carbon. There was a significant difference of porous between two image corresponding modification
