TL;DR: In this paper, the authors discuss the importance of statistical parameters such as coefficient of determination (R^{2} ), adjusted coefficient of determinant (R_{\text{adj}}^{2}) and standard deviation (root of mean square error) for determining whether an adorption process is a chemical or a physical process.
Abstract: In adsorption study, isotherms and kinetics of adsorption process provide pieces of information underlying the mechanisms and dynamics of the process. Several equilibrium and kinetic models are usually employed for performing the experimental design of an adsorption system. In this chapter, the Langmuir, Freundlich, Sips, Liu, Redlich–Peterson nonlinear equations, as well as other unusual isotherm models (Hill, Khan, Radke–Prausnitz, Toth) are discussed. For the kinetics of adsorption, the pseudo-first-order, pseudo-second-order, general-order, Avrami fractionary order, and Elovich chemisorption models are explained. The importance of statistical parameters such as coefficient of determination (\(R^{2}\)), adjusted coefficient of determination (\(R_{\text{adj}}^{2}\)), and standard deviation (root of mean square error) are highlighted. The usage of linearized and nonlinearized equations are illustrated and explained. Some common mistakes commonly committed in the literature using linearized equilibrium and kinetic adsorption models as well as other polemic points in adsorption research are pointed out. Analytical techniques together with thermodynamical data of enthalpy and entropy changes are needed to ascertain if an adsorption process is a chemical or a physical process.

TL;DR: A review of common kinetic models for liquid adsorption can be found in this paper, where the authors discuss their origins, features, modified versions, applicability, and applicability with regard to liquid adaption modeling for both batch and dynamic systems.
Abstract: The past decade has seen a boom in environmental adsorption studies on the adsorptive removal of pollutants from the aqueous phase. A large majority of works treat kinetic modeling as a mere routine to describe the macroscopic trend of adsorptive uptake by using common models, often without careful appraisal of the characteristics and validity of the models. This review compiles common kinetic models and discusses their origins, features, modified versions (if any), and applicability with regard to liquid adsorption modeling for both batch adsorption and dynamic adsorption systems. Indiscriminate applications, ambiguities, and controversies are highlighted and clarified. The appropriateness of linear regression for correlating kinetic data is discussed. This review concludes with a note on the current scenario and the future of kinetics modeling of liquid adsorption.
