WebJan 2, 2024 · The C-shaped isotherms reflect that ions are non-specifically adsorbed on the adsorption sites (Sparks 2003). The amount of Ca in both exchange and solution phases increased with increasing initial concentration in the equilibrating solution and reached the maximum values when the solution containing 600 mg L −1 of Ca was added to soils. WebThe inner Helmholtz plane is defined by specifically adsorbed ions that are tightly bound to the surface at a short distance. These ions are partly dehydrated. Following this plane of specifically adsorbed ions are counterions which are non-specifically adsorbed and are fully hydrated. This defines the outer Helmholtz plane.
