Parameter Identification of the Langmuir Model for Adsorption and Desorption Kinetic Data

In this work, we model adsorption and desorption kinetic data of spin-coated 50 nm Ruthenium polypridyl complex (Ru-PC K314) film by nonlinear regression methodology. The data is measured by an extensively used technique which is called Quartz Crystal Microbalance. We reported that adsorption rate k a is same for both adsorption and desorption of Ruthenium polypridyl complex film.
