partial isotherm (individual isotherm)

in surface chemistry
https://doi.org/10.1351/goldbook.P04412
The function relating, at constant temperature and pressure, the amount of a particular component in the
interfacial layer
per unit area (or per unit mass of
adsorbent
) with its
mole fraction
(or concentration) in the liquid phase. This function can be evaluated only when the location and the thickness of the
interfacial layer
have been defined.
