Jovanovic Isotherm Non-Linear Analysis

Description

The Jovanovic isotherm model was built upon the assumptions based on the Langmuir isotherm model with few possible inclusions of mechanical contact among the desorbing and adsorbing molecules. The adjustment of the adsorption surface from this model made the equation less effective in the physical adsorption but can be applied to adsorption with both mobile and localized monolayer without lateral interaction. Moreover, the equation of the Jovanovic isotherm model is able to reach the limit of saturation when there is high concentration, while it reduces to Henry's Law at low concentration.
