elovichanalysis: Elovich Isotherm Analysis Non-Linear Form

Description

Elovich empirical adsorption model is based on the assumption of energetic heterogeneity of the adsorption sites. Moreover, elovich maximum adsorption capacity and Elovich constant can be calculated from the slopes and the intercepts of the plot ln(Qe/Ce) versus Qe.

Usage

elovichanalysis(Qe, Ce)

Arguments

Qe

the numerical value for adsorbed capacity

Ce

the numerical value for equilibrium concentration

Value

the linear regression and the parameters for the Elovich isotherm
