摘要：

This article undertakes a critical evaluation of the literature regarding the use of the Langmuir isotherm, specifically in the context of inhibitor research. The Langmuir isotherm is frequently employed to derive thermodynamic and kinetic parameters, which are then used to gauge inhibitor performance. However, the validity of the Langmuir isotherm has been challenged, particularly by Walczak et al. (2019), whose work has served as a basis for others to reject its use as inadequate. Imposing limitations on the Langmuir isotherm would involve restrictions on heterogeneous kinetics, impedance interpretation, and other transient techniques. These aspects will be subjected to a more in-depth analysis in this discussion paper.
