Centenary of Langmuir Isotherm

Journal of Surface Science and Technology, 2019
Irving Langmuir published a seminal paper, on the adsorption of gases at a constant temperature in 1918, which presented one of the most important isotherm equations available in post Langmuir era. Many other useful isotherm equations were suggested both before and after 1918.

Isosteric heat of adsorption from thermodynamic Langmuir isotherm

Adsorption, 2021
The recently developed thermodynamic Langmuir isotherm model is used to estimate the isosteric heat of adsorption for pure component adsorption. Specifically, pure component adsorption isotherms at different temperatures are first correlated with the thermodynamic Langmuir isotherm model.

Langmuir isotherm explains maximum foamability

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2016
Abstract The relevant and promising empirical observation of M. Rosen regarding the maximum foam height in a column at the critical micelle concentration is explained using basic thermodynamic analysis. Elasticity determined isothermally from the equilibrium π − A curve and Gibbs elasticity modulus, is evaluated by means of the Langmuir isotherm ...

A Sorbent Concentration-Dependent Langmuir Isotherm

Acta Physico-Chimica Sinica, 2012
Batch adsorption experiments of Pb(II) and Cu(II) on kaolinite as a function of kaolinite concentration were conducted. An obvious sorbent concentration effect (Cs-effect) was observed; namely, the adsorption isotherm declines as sorbent concentration (Cs) increases. The experimental data were fitted to the classic Langmuir model.

Determination of thermodynamic parameters from Langmuir isotherm constant-revisited

Journal of Molecular Liquids, 2017
Abstract An analytical approach for estimation of the thermodynamic parameters from the Langmuir isotherm constant has been introduced in the present paper. The concept of the thermodynamic equilibrium constant for the Langmuir isotherm based adsorption process was critically analysed.

Some consideration on the Langmuir isotherm equation

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2006
Abstract The Langmuir isotherm equation has been widely used in adsorption process for decades. This note analyzed application constrain of the Langmuir isotherm equation. In a strict theoretical sense, the concentration of adsorbate used in the Langmuir isotherm equation must be expressed as its molar concentration.
