Webhere, K is surface concentration-dependent affinity parameter. Also, b is a parameter, which accounts for the changing energies of adsorption due to the change of surface coverage. If b = 0, K = K L, and Eq. (6.30) becomes the Langmuir isotherm. The modified Langmuir isotherm of Gu et al. is capable to model a wide variety of isotherms systems. Fig. 6.3 … WebThe Freundlich adsorption isotherm is followed by another two isotherms, Langmuir adsorption isotherms and BET theory. The Langmuir adsorption isotherms predict linear adsorption at low adsorption densities and a …
