Langmuir Isotherm Model

Description

The Langmuir isotherm assumes monolayer adsorption onto a surface with a finite number of identical sites. It is characterized by uniform energies of adsorption onto the surface and no transmigration of adsorbate in the plane of the surface. The model is described by the equation:

Q = \frac{Q_{\max} \cdot K_L \cdot C_e}{1 + K_L \cdot C_e}

where Q is the amount adsorbed, C_e is the equilibrium concentration, Q_{\max} is the maximum adsorption capacity, and K_L is the Langmuir constant.

For more information, see Langmuir (1918): \Sexpr[results=rd]{tools:::Rd_expr_doi("https://doi.org/10.1021/ja02242a004")}

Usage

langmuir_model(Ce, Qe)

Arguments

Ce	Numeric vector of equilibrium concentrations.
Qe	Numeric vector of amount adsorbed.

Value

A named list of Langmuir parameters and model details.

Examples

Ce <- c(1, 2, 3, 4, 5)
Qe <- c(0.8, 1.5, 2.1, 2.6, 2.9)
result <- langmuir_model(Ce, Qe)
print(result)
