Langmuir Moisture Sorption Isotherm

Description

Langmuir Isotherm is a two-parameter model applicable for unimolecular layers with similar sorption sites. Langmuir's isotherm is the most crucial equation among the theoretical models, whose basis are the forces acting between the product surface and the condensed water from the vapor as a monomolecular layer.

Usage

LangmuirMSI(WaterAct, AdsorpM, DesorpM)

Arguments

WaterAct	the numerical value of Water Activity, which ranges from 0 to 1.
AdsorpM	the numerical value of the Moisture content of the Adsorption curve, which ranges from 0 to 1.
DesorpM	the numerical value of the Moisture content of the Desorption curve, which ranges from 0 to 1.

Value

the nonlinear regression, parameters, and graphical visualization for the Langmuir Moisture Sorption Isotherm model.
