Koble-Carrigan Isotherm Nonlinear Analysis

Description

It is three-parameter isotherm model equation that incorporates both Freundlich and Langmuir isotherms for representing equilibrium adsorption data. Koble-Corrigan isotherm model appeared to have advantages over both the Langmuir and Freundlich equations in that it expresses adsorption data over very wide ranges of pressures and temperatures.

Usage

koblecarrigananalysis(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 Koble-Carrigan isotherm, and model error analysis
