.. _multi_component_colloidal_config: Multi Component Colloidal ~~~~~~~~~~~~~~~~~~~~~~~~~ **Group /input/model/unit_XXX/adsorption – ADSORPTION_MODEL = MULTI_COMPONENT_COLLOIDAL** ``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. =================== ========================= ========================================= **Type:** int **Range:** {0,1} **Length:** 1/NTOTALBND =================== ========================= ========================================= ``COL_PHI`` Phase ratio :math:`\Phi` **Unit:** :math:`m^{2} m_{s}^{-3}` =================== ========================= ========================================= **Type:** double **Range:** :math:`\ge 0` **Length:** 1 =================== ========================= ========================================= ``COL_KAPPA_EXP`` Screening term exponent factor :math:`\kappa_{ef}` =================== ========================= ========================================= **Type:** double **Range:** :math:`\ge 0` **Length:** 1 =================== ========================= ========================================= ``COL_KAPPA_FACT`` Screening term factor :math:`\kappa_{f}` **Unit:** :math:`m \cdot mM^{-1}` =================== ========================= ========================================= **Type:** double **Range:** :math:`\ge 0` **Length:** 1 =================== ========================= ========================================= ``COL_KAPPA_CONST`` Screening term constant :math:`\kappa_{c}` **Unit:** :math:`m` =================== ========================= ========================================= **Type:** double **Range:** :math:`\ge 0` **Length:** 1 =================== ========================= ========================================= ``COL_CORDNUM`` Coordination number :math:`n` =================== ========================= ========================================= **Type:** int **Range:** :math:`\ge 0` **Length:** 1 =================== ========================= ========================================= ``COL_LOGKEQ_PH_EXP`` Protein-resin interaction :math:`K_{e,i}` equilibrium: Constant exponent :math:`k_{e,i}` for pH If pH is not considered, this value will be not be used but must still be specified, i.e. can be any number. =================== ========================= ========================================= **Type:** double **Range:** :math:`\ge 0` **Length:** NTOTALBND =================== ========================= ========================================= ``COL_LOGKEQ_SALT_POWEXP`` Protein-resin interaction :math:`K_{e,i}` equilibrium: Constant pre-factor :math:`k_{a,i}` for salt power =================== ========================= ========================================= **Type:** double **Range:** :math:`\ge 0` **Length:** NTOTALBND =================== ========================= ========================================= ``COL_LOGKEQ_SALT_POWFAC`` Protein-resin interaction :math:`K_{e,i}` equilibrium: Constant exponent :math:`k_{b,i}` for salt power =================== ========================= ========================================= **Type:** double **Range:** :math:`\ge 0` **Length:** NTOTALBND =================== ========================= ========================================= ``COL_LOGKEQ_SALT_EXPFAC`` Protein-resin interaction :math:`K_{e,i}` equilibrium: Constant pre-factor :math:`k_{c,i}` for e-function with salt power =================== ========================= ========================================= **Type:** double **Range:** :math:`\ge 0` **Length:** NTOTALBND =================== ========================= ========================================= ``COL_LOGKEQ_SALT_EXPARGMULT`` Protein-resin interaction :math:`K_{e,i}` equilibrium: Constant power factor :math:`k_{d,i}` for salt in e-function =================== ========================= ========================================= **Type:** double **Range:** :math:`\ge 0` **Length:** NTOTALBND =================== ========================= ========================================= ``COL_BPP_PH_EXP`` Protein-protein interaction :math:`b_{pp,i}`: Constant power term :math:`b_{e,i}` for pH.
