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

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.
