SORPTION EQUILIBRIUM
SORPTION EQUILIBRIUMThe quantity of a solute adsorbed can be defined conveniently in terms of moles or volume (for adsorption) or ion equivalents (for ion exchange) per unit mass or volume (dry or wet) of sorbent. Common units for adsorption are mol/(m3 of fluid) for the fluid-phase concentration ci and mol/(kg of clean adsorbent) for adsorbed-phase concentration ni. For gases, partial pressure may replace concentration.Many models have been proposed for adsorption and ion exchange equilibria. The most important factor in selecting a model from an engineering standpoint is to have an accurate mathematical description over t…
