Elovich Isotherm Non-Linear Analysis

Description

Elovich isotherm model is based on kinetic principle which assumes that the adsorption sites would exponentially increase with chemical reactions responsible for adsorption. It is suited for describing the behavior of adsorption concurring with the nature of chemisorption.

Usage

elovichanalysis(Ce, Qe)

Arguments

Ce

the numerical value for equilibrium concentration

Qe

the numerical value for adsorbed capacity

Value

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