Freundlich isotherm

The Freundlich isotherm model is one of the first published models for use with heterogeneous surfaces.

freundlichThe Freundlich isotherm may be transformed to a linear equation and the constants K and n are readily determined.

freun_linA value of 1/n less than 1.0 implies chemisorption and values greater than 1.0 may be indicative of cooperative adsorption.  The Freundlich isotherm is part of the standard Micromeritics physical adsorption isotherm modelling package and has also been added to MicroActive.
