temkin_model: Temkin Isotherm Model

In AdsorpR: Adsorption Isotherm Models

Temkin Isotherm Model

Description

The Temkin isotherm considers the effects of indirect adsorbate/adsorbate interactions. It assumes that the heat of adsorption of all molecules in the layer decreases linearly with coverage (Temkin and Pyzhev 1940). The model is given by: Q = (RT / bT) * ln(AT * Ce)

Usage

temkin_model(Ce, Qe, R = 8.314, T = 298)

Arguments

Ce	Numeric vector of equilibrium concentrations.
Qe	Numeric vector of amount adsorbed.
R	Universal gas constant.
T	Temperature in Kelvin.

Value

A named list of Temkin parameters and model details.

result <- temkin_model(Ce, Qe)
print(result[1:2])
