Affinity Complex Titration
==========================

**Group /input/model/unit_XXX/adsorption – ADSORPTION_MODEL = AFFINITY_COMPLEX_TITRATION**

For information on model equations, refer to :ref:`affinity_complex_titration`. The first component should be pH. 


``IS_KINETIC``
   Selects kinetic or quasi-stationary adsorption mode: 1 = kinetic, 0 =
   quasi-stationary. If a single value is given, the mode is set for all
   bound states. Otherwise, the adsorption mode is set for each bound
   state separately.
