Reply To Comment on "Langmuir Adsorption Kinetics in Liquid Media: Interface Reaction Model"

Area of Science:

• Environmental Science
• Chemical Engineering
• Geochemistry

Background:

• A prior study introduced an interface reaction model (IRM) to calculate sorption-desorption rate constants independent of operational variables.
• Recent commentary questioned the IRM's implicit assumptions and dimensional homogeneity.

Purpose of the Study:

• To address recent commentary regarding the interface reaction model (IRM).
• To demonstrate the dimensional consistency of the IRM equations.
• To clarify the dimensions of each term within the IRM.

Main Methods:

• The authors re-evaluated the implicit assumptions in the IRM development.
• A detailed analysis of the dimensional homogeneity of the IRM equations was performed.

Main Results:

• The authors concur with the simplifications made during the IRM's development.
• The IRM equations were confirmed to be dimensionally consistent.
• A comprehensive discussion on the dimensions of each term in the IRM was provided.

Conclusions:

• The interface reaction model (IRM) is a valid tool for determining sorption-desorption rate constants.
• The dimensional consistency of the IRM has been rigorously demonstrated.
• This work aims to prevent future confusion regarding the model's dimensional integrity.
