Freundlich Isotherm Analysis Linear Form

Description

This isotherm model predicts the logarithmic relationship of equilibrium capacity and adsorbed capacity (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

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 and the parameters for the Freundlich isotherm
