Freundlich Isotherm 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

freundlich.LM(Ce, Qe)

Arguments

Ce

the numerical value for the equilibrium capacity

Qe

the numerical value for the adsorbed capacity

Value

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