Langmuir Isotherm Nonlinear Analysis

Description

The Langmuir isotherm is described to be the most useful and simplest isotherm for both chemical adsorption and physical adsorption. It assumes that there is uniform adsorption energy onto the monolayer surface and that there would be no interaction between the adsorbate and the surface.

Usage

langmuiranalysis(Ce, Qe)

Arguments

Ce

the numerical value for the equilibrium capacity

Qe

the numerical value for the adsorbed capacity

Value

the nonlinear regression, parameters for Langmuir isotherm, and model error analysis
