Characterization of Molecularly Imprinted Polymers with the Langmuir−Freundlich Isotherm

Analytical Chemistry, 2001
The majority of binding models that have been applied to molecularly imprinted polymers (MIPs) have been homogeneous models. MIPs, on the other hand, are heterogeneous materials containing binding sites with a wide array of binding affinities and selectivities.

Natural Organic Matter Sorption by Kaolinite: Modified Langmuir Isotherm

Journal of Environmental Engineering, 1997
This technical note describes the use of the modified Langmuir isotherm (MLI) model recently introduced by Gu and coworkers to describe the adsorption and desorption of natural organic matter (NOM) onto Kaolinite. The MLI was able to describe the adsorption of two different NOM samples with the use of three adjustable parameters.

On the derivation of the Langmuir adsorption isotherms

Kolloid-Zeitschrift & Zeitschrift für Polymere, 1965
An intermediate relation obtained byJellinek in his derivation of theLangmuir adsorption isotherm equation is found to be equivalent tode Witte's extension ofJ. J. Thomson's adsorption theorem. To transform this relation into theLangmuir equationJellinek assumes the quantity\(b' = \frac{{RT}}{b}e^{\frac{{ - \Delta W_\alpha }}{{RT}}} \), to be a ...

Application of Langmuir isotherm to saturated fatty acid adsorption

Microporous and Mesoporous Materials, 2006
Abstract Adsorption of saturated fatty acids (C10, C12, C14, C16 and C18) was carried out on montmorillonite. The adsorption of fatty acids on a clay mineral (montmorillonite) was investigated at 25 ± 0.5 °C using different weights of the clay (0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7 and 0.8 g).

Gaseous slip models based on the Langmuir adsorption isotherm

Physics of Fluids, 2004
On the basis of Langmuir’s theory of adsorption of gases on solids, a robust gaseous slip model is presented. The concept of accommodation coefficient and the difference of gas particles are explained within the new framework. It turned out that the Langmuir model recovers the Maxwell model in the first-order approximation in the case of the ...

Solvent gradient operation of simulated moving beds. 2. Langmuir isotherms.

Journal of chromatography. A, 2004
Simulated Moving Bed separations of enantiomers or fine chemicals are usually carried out in the isocratic mode, i.e. by applying the same operating conditions (temperature, pressure, mobile phase composition, pH) in the whole SMB unit. However, it has been recently recognized that by properly modulating operating conditions in the SMB sections.
