摘要：

There is great ambiguity in the calculation of adsorption equilibrium constant and thermodynamic parameters (Delta G(theta), Delta H-theta, and Delta S-theta). The calculation of Delta G(theta), Delta H-theta, and Delta S-theta requires the dimensionless standard equilibrium constant. The experimental equilibrium constant should be converted to the standard equilibrium constant by the standard state. The choice of standard state affects the value of the Delta G(theta), Delta H-theta, and Delta S-theta. The corresponding adsorption equation should also be clarified. The calculation method of equilibrium constant for various isotherm models mentioned are provided. (C) 2020 Elsevier B.V. All rights reserved.
