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
