freundlichanalysis: Freundlich Isotherm Analysis Non-Linear Form

Description

This isotherm model is an empirical model applicable to diluted solutions adsorption processes (Gessner and Hasan, 1987). Furthermore, this model gives an equation which defines the surface heterogeneity and the exponential distribution of active sites (Ayawei, et al., 2017).

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 and the parameters for the Freundlich isotherm
