Using the phenomenological-thermodynamics method, we have 
derived an equation which is one possible form of representation of 
interphase equilibrium. It has been shown that this equation yields, 
as particular cases, the well-known equations of Henry, Langmuir, 
Fowler-Guggenheim, Temkin, and Brunauer-Emmett-Teller. 
The equation proposed can provide a basis for simulating adsorption 
and absorption processes in highly diverse systems, including swelling 
ones.
