Web30 aug. 2024 · At very low protein concentrations, the adsorption of these proteins was earlier described by Langmuir-type adsorption isotherms. However, when the protein concentration is raised, the adsorption data are found to fit the BET (Brunauer, Emmett, and Teller) adsorption isotherm well, indicating multilayer formation on the GNP surface. Web30 sept. 2024 · The theoretical equation of this multilayer model presents numerous physicochemical parameters that can be determined from the experimental data of … WebThe calculated multilayer adsorption isotherm for water was identical for Li-, Ca-, Ba-, and Al-kaolinites. The same isotherm also described water adsorption by Na-kaolinites up to P/P o = 0.9 where ion hydration was initiated. A definite effect on the parameters of the FHH equation was found as the nature of the substrate surface was varied ... mary brandon park west palm beach
