langmuirFanalysis: Langmuir-Freundlich Isotherm Analysis Non-Linear Form

Description

Langmuir-Freundlich Isotherm Analysis describes the distribution of adsorption energy onto heterogeneous surfaces of the adsorbent. At low concentrations of adsorbate, this model becomes Freundlich isotherm, and then at high concentration of adsorbate, it becomes the Langmuir Isotherm. The parameters of this concentration can be obtained using the non-linear regression.

Usage

langmuirFanalysis(Ce, Qe)

Arguments

Ce

the numerical value for the equilibrium capacity

Qe

the numerical value for the adsorbed capacity

Value

the linear regression and the parameters for the Langmuir-Freundlich isotherm
