In many reactive transport simulations and geochemical box models, these sorption processes are modeled using a simple distribution coefficient \[Kd\ =\ {Msolid}{Mₛₒₗᵤₜᵢₒₙ}\] (1) where Msolid is the mass concentration of component i in the solid and Msolution is the mass concentration of i in the aqueous solution. However, this approach fails to give a correct description of reactive transport (Brady and Bethke 2000). Even in simple batch simulations (no transport), the...
