Freundlich adsorption equation

The Freundlich adsorption equation describes how a substance, called an adsorbate, sticks onto a surface, like dirt on a filter. It shows that the amount of adsorbate on the surface increases with its concentration in the surrounding fluid, but at a decreasing rate. This means that as more adsorbate binds, it becomes harder for additional molecules to attach. The equation includes factors like the surface's ability to attract molecules and how strongly they bind. It's useful for understanding processes like water purification or pollution control, where materials capture contaminants from liquids or gases.
