Langmuir Adsorption Isotherm

The Langmuir Adsorption Isotherm describes how molecules from a fluid (like gas or liquid) stick to a solid surface. It assumes that the surface has a fixed number of sites for molecules to attach and that each site can hold only one molecule. When the surface becomes covered, fewer spots are available, so the amount of adsorbed molecules levels off, reaching a maximum. This model helps predict how much of a substance will stick to a surface at different concentrations, important in areas like purification, catalysis, and sensors.
