A Freundlich-type multicomponent isotherm

Journal of Colloid and Interface Science, 1981
Abstract A multicomponent adsorption isotherm is derived based on the assumption that an exponential distribution of adsorption energies exists for each component. A prerequisite for the application of the isotherm is that each component individually obey the Freundlich isotherm.

Freundlich's Isotherm Extended by Statistical Mechanics

Journal of Colloid and Interface Science, 1997
In this paper we obtain an asymptotic development compatible with Freundlich's isotherm, theta = KCm. That expression was derived underlying the theory of heterogeneous surface. We assume the distribution function of adsorption sites to be in the exponential form and the sites to follow the Langmuir energy homogeneous isotherm.

A sorbent concentration-dependent Freundlich isotherm

Colloid and Polymer Science, 2012
During study of the adsorption isotherms at solid–liquid interfaces, a sorbent concentration effect (Cs-effect) phenomenon was observed. In order to describe the Cs-effect, we proposed a new adsorption model, i.e., surface component activity (SCA) model. It supposes that the interaction between the sorbent particles exists in the real adsorption system,

The Freundlich Isotherm in Studying Adsorption in Oil Processing

Journal of the American Oil Chemists' Society, 1996
AbstractThe objective of this review is to discuss the history of the use of the Freundlich isotherm in investigating adsorption processing of vegetable oils and to evaluate its current value in adsorption studies. The Freundlich isotherm was originally developed to explain the adsorption of a single solute from solution.

Tylosin sorption to diatomaceous earth described by Langmuir isotherm and Freundlich isotherm models

Chemosphere, 2018
Tylosin, an antibiotic used for maintaining livestock health, is a macrolide structurally similar to a number of important, often prescribed human antibiotics. Because of this relationship, tylosin presents a potential threat of antimicrobial resistance from environmental buildup.
