Competitive Adsorption of Metals onto Magnetic Graphene Oxide: Comparison with Other Carbonaceous Adsorbents

Figure 6

The evaluation index (a) for SRFA effects on metal adsorption on magnetic GO (a), PAC (b), and MWCNT (c) as a function of the initial metal concentrations (). The first three data points of Pb(II) on the magnetic GO were neglected because of the extremely low equilibrium concentrations ().
