Abstract Water pollution is an increasingly serious problem the world is facing today, causing damage to human health and ecological environment. Adsorption is one of the most commonly used techniques for water purification due to its high efficiency, low cost, easy operation and environmental benign properties. Thermodynamic parameters such as the Gibbs free energy change (ΔG⁰), enthalpy change (ΔH⁰) and entropy change (ΔS⁰) are critical in estimating the performance and predicting the mechanism of an adsorption process. In the adsorption literature, thermodynamic parameters are usually improperly calculated, and the results are unreliable. The reason is the standard equilibrium constant for calculation ΔG⁰ must be a dimensionless parameter. The Langmuir equation is the most widely used isotherm equation in the adsorption process. By deducing the standard equilibrium constant K⁰ and the Langmuir equilibrium constant K_L, the physical significances of the two parameters were identified and the conversion relationship between them were discussed. Moreover, the existing problems in the literature were summarized and corrected. This study attempts to shed light on the proper estimation of thermodynamic parameters in the adsorption process.
