Sorption process 206 stability constant

Finally, some formulas and stability constants of (hypothetical) surface species (or Gibbs energies of adsorption) are reported in Tables 4.1-4.4. These quantities belong to adsorption models proposed by the authors of cited publications, but they are not sufficient to calculate the uptake curves or adsorption isotherms when the model involves an electrostatic factor. Adsorption models themselves are not discussed in the present chapter, their terminology is explained in detail in Chapter 5, In contrast with the directly measured quantities that represent the sorption properties at specific experimental conditions, the model parameters characterize the sorption process over a wide range of experimental conditions, although the match between experimental and theoretically calculated quantities was not always... [Pg.354]

According to the previous classifications,also other adsorption processes can be distinguished—mainly for chenficaUy modified electrodes, CMEs—depending on the accumulation principles, electrode surface conditions and actual chemical equilibria (always, in close relation with solubility products, pKs, or conditional stability constants ). Together with the already introduced schemes (Eqs. 5.6a-5.6c), there are the following possible sorption mechanisms (Eqs. 5.8a-5.11) ... [Pg.98]
