Langmuir Isotherm Nonlinear Analysis via selfStart and Langmuir Second Linear Model

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

SSLangmuir2analysis(Ce, Qe)

Arguments

Ce

the numerical value for the equilibrium capacity

Qe

the numerical value for the adsorbed capacity

Value

the nonlinear regression via selfStart, initial starting values for parameters based on Langmuir second linear model, predicted parameter values, and model error analysis
