Freundlich isotherm
The Freundlich isotherm is a model that describes how substances, like pollutants or minerals, interact with surfaces, such as soil or activated carbon. It explains how the amount of substance that attaches to a surface varies with its concentration in the surrounding environment. Unlike some other models, the Freundlich isotherm assumes that this relationship is nonlinear, meaning that as concentration increases, the rate of uptake changes. It's useful for understanding adsorption in various fields, including environmental science, chemistry, and engineering, helping to design better systems for cleaning or filtering substances from liquids or gases.
