A New Theoretical Study of Desorption Kinetics at Solid/Solution Interface by Statistical Rate Theory

Desorption is one of the popular methods for the design and regeneration of catalysts. For better understanding and modeling of this process, it is important to have models with theoretical basis. In the present work kinetics of solute desorption at solid/solution interface has been studied by statistical rate theory (SRT) when the system is close to equilibrium. Based on numerically generated points (t; q) by the SRT equation, it has been shown that the results of numerical analysis are in good agreement with our theoretical derivation of new rate equation for desorption systems close to equilibrium. Finally the results of the present theoretical study were confirmed by analysis of two experimental systems.
