Modeling the adsorption of hydrogen, sodium, chloride and phthalate on goethite using a strict charge-neutral ion-exchange theory
Fig 5
Adsorption of H+, Na+, Cl− and phthalate (L2–) ions on goethite using the competitive ion-exchange model described in Table 2.
The aqueous phase protonation reactions of phthalate ions were also included in the model. Symbols: solid = H+, circles = Cl−, triangles = L2–. The curves shown were generated and optimized using IExFit software.
