Fowler-Guggenheim Isotherm Non-Linear Analysis
Description
In Fowler-Guggenheim isotherm model, the lateral interaction of the adsorbed molecules is taken into consideration. This is formulated on the basis that the heat adsorption process may vary positively or negatively with loading.
Usage
fowlerguggenheimanalysis(Ce, theta, Temp)
Arguments
Ce |
is equal to Co which is the numeric value for the initial concentration |
theta |
is the fractional surface coverage |
Temp |
temperature |
Value
the nonlinear regression, parameters for Fowler-Guggenheim isotherm, and model error analysis
