Hill-Deboer Isotherm Non-Linear Analysis
Description
Hill-Deboer isotherm model describes as a case where there is mobile adsorption as well as lateral interaction among molecules.The increased or decreased affinity depends on the kind of force among the adsorption molecules. If there is an attraction between adsorbed molecules, there is an increase in affinity. On the other hand, decreased affinity happens when there is repulsion among the adsorbed molecules.
