Equilibrium Dynamics of Ion Sorption and Standard Quasi-Equilibrium Frontal Chromatography

Sorption in columns is said to be dynamic as opposed to static, the latter occurring in vessels in which the sorbents and solution are agitated. The difference between the two is that in dynamic sorption the equilibrium is established with the initial solution in most of the column (above the sharp front), while in static sorption the solution is gradually depleted of sorbate and the equilibrium is finally established with a solution that has a different composition than the one originally added to the vessel. A natural result is that the static sorption capacity is lower than the dynamic one, and not just for molecular adsorption, but for ion exchange too.
