Bradley Moisture Sorption Isotherm
Description
Bradley model is a two-parameter isotherm model that measures polar nature of sorptive surfaces.
Usage
BradleyMSI(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 Bradley Moisture Sorption Isotherm model.
