LNLM: Langmuir Nonlinear Model

Description

This model will fit the adsorption data to the nonlinear form of the Langmuir equation and will give the estimates of the Langmuir parameters, namely "b" and "k" while evaluating the performance efficiency of the nonlinear model of Langmuir through several error functions.

Usage

LNLM (ce, qe)

Value

• Langmuir Isotherm Nonlinear Model: Model summary

• correlation (ce, qe): Correlation between ce and qe

• b: Adsorption maxima

• k: Langmuir adsorption constant related to bonding energy

• AIC: Akaike information criterion

• AICc: Corrected Akaike information criterion

• BIC: Bayesian information criterion

• RMSE: Root Mean Squared Error

• MSE: Mean Squared Error

• MAE: Mean Absolute Error

• MAPE: Mean Absolute Percentage Error

• Chi.square: Chi-square value

Arguments

ce

Equilibrium concentration of the adsorbate in the solution

qe

Amount adsorbed
