Freundlich

The Freundlich model describes how substances like nutrients or pollutants are absorbed or interact with surfaces, such as soil or materials. It’s based on the idea that the amount of substance taken up increases with its concentration but at a decreasing rate—meaning, as the concentration gets higher, each additional amount is absorbed less efficiently. This relationship is expressed mathematically with an equation that relates the amount absorbed to the concentration, helping scientists predict and analyze how substances behave in different environments or systems.
