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.

Usage

hilldeboeranalysis(Ce, theta, Temp)

Arguments

Ce	the numerical value for the equilibrium capacity
theta	is the fractional surface coverage
Temp	the temperature of the adsorption experimentation in Kelvin

Value

the nonlinear regression, parameters for the Hill-Deboer isotherm, and model error analysis
