In physical chemistry, the Polanyi potential theory, also called Polanyi's potential theory of adsorption or Eucken–Polanyi potential theory, is a model of adsorption proposed independently by Michael Polanyi and Arnold Eucken. Under this model, adsorption can be measured through the equilibrium between the chemical potential of a gas near the surface and the chemical potential of the gas from a large distance away.
