Study Cards on sorption, langmuir, permeant

If you want to know the concentrations valid for a barrier systems, which 3 sorption isotherms do you have?
  1. Phase rich in permeant
  2. Phase poor in permeant
  3. Barrier phase
When can you apply the Henry model?
For simple liquids; dilute systems
When can you apply the Langmuir model?
For monolayer adsorption; surfaces and porous systems; some glassy polymers
When can you apply the multilayer adsorption model?
For polymeric materials and solutions (combination of Henry and Langmuir sorption)
When can you apply the GAB model?
For multilayer sorption; food matrices
