Freundlich isotherm parameters

Figure 4 Comparison of sorption models. Several commonly used sorption models are compared with respect to the independent constants they require. These constants are vahd only under specific conditions, which must be specified in order to properly use them. In other words, the constants are conditional with respect to the experimental variables described in the third column of the figure. is the radionuclide distribution constant K and n are the Freundlich isotherm parameters and are surface complexation constants for protonation and deprotonation of surface sites K-, are surface complexation constants for sorption of cations and anions in the constant...

Figure 4 Comparison of sorption models. Several commonly used sorption models are compared with respect to the independent constants they require. These constants are valid only under spedlic conditions, which must he specified in order to properly use them. In other words, the constants are conditional with respect to the experimental variables described in the third column of the figure. is the radionuclide distrihution constant K and n are the Freundlich isotherm parameters and f3 are surface complexation constants for protonation and deprotonation of surface sites K, K-, 13, are surface complexation constants for sorption of cations and anions in the constant capacitance model and TLM, respectively C, Ci, and are capacitances for the electrical double layers rr, ov, and oj, are surface charges at different surface planes (Me) and (S) are concentrations of the sorbing ions and the surface sites, (M), (L) are concentrations of other cations and ligands in solution, respectively I is the ionic strength of the background electrolyte and 5a are the site density and specific surface of the substrate, respectively. The requirements of the DLM are similar to those of the constant capacitance model.
