Freundlich Isotherm Non-Linear Analysis

Description

This isotherm model is an empirical model applicable to diluted solutions adsorption processes. Furthermore, this model gives an equation which defines the surface heterogeneity and the exponential distribution of active sites.

Usage

freundlichanalysis(Ce, Qe)

Arguments

Ce	the numerical value for the equilibrium capacity
Qe	the numerical value for the adsorbed capacity

Value

the nonlinear regression, parameters for Freundlich isotherm, and model error analysis
