Model

Qa (g/g)

Monolayer (Model 1)

\(Q_{a} = \frac{{n.D_{M} }}{{\left( {1 + \left( {\frac{{P_{1/2} }}{P}} \right)} \right)}}\) (1)

Two layer with two energies (Model 2)

\(Q_{a} = n.D_{M} \frac{{\left( {\frac{p}{{P_{1} }}} \right)^{n} + 2.\left( {\frac{p}{{P_{2} }}} \right)^{2n} }}{{1 + \left( {\frac{p}{{P_{1} }}} \right)^{n} + \left( {\frac{p}{{P_{2} }}} \right)^{2n} }}\) (2)
