The adsorption on the solid-liquid interface is important for industry and daily life. To investigate the adsorption process, the adsorption thermodynamics usually are essential. The adsorption thermodynamics are analyzed with the parameters of the change of Gibbs free energy (ΔG), enthalpy (ΔH), and entropy (ΔS). In this presentation, the different methods for calculation of the adsorption thermodynamics parameters are introduced. Moreover, examples for calculations and applications of the adsorption thermodynamics are presented.

Key words: Adsorption, Thermodynamics, Thermodynamics parameter
