freundlich_model: Freundlich Isotherm Model

In AdsorpR: Adsorption Isotherm Models

Freundlich Isotherm Model

Description

Freundlich isotherm describes adsorption on heterogeneous surfaces and assumes that the stronger binding sites are occupied first (Freundlich, 1907). It is represented by: Q = Kf * Ce^(1/n) where Kf is the Freundlich constant related to adsorption capacity and n indicates adsorption intensity. https://doi.org/10.1002/ange.19070201805

Usage

freundlich_model(Ce, Qe)

Arguments

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

Value

A named list of Freundlich parameters and model details.
