fit_freundlichNLM: Freundlich Isotherm Non-Linear Analysis

Description

Performs non-linear modeling for the Freundlich adsorption isotherm.

Value

A list containing the results of the non-linear Freundlich model fitting, including:

  • Parameter estimates for the Freundlich model (KF and n).

  • Fit statistics such as Akaike Information Criterion (AIC), Bayesian Information Criterion (BIC), and R-squared.

  • Error metrics including Root Mean Square Error (RMSE), Mean Absolute Error (MAE), Mean Squared Error (MSE), Relative Absolute Error (RAE), and standard error of estimates.

  • A model fit plot with bootstrapped 95

  • A residual plot for diagnostic assessment of model performance.

Arguments

Ce

numeric vector for equilibrium concentration

Qe

numeric vector for adsorbed amount
