Here is the initial molar concentration of the inert component in the gas
mixture. It is subject to the condition Neglecting adsorption
of the inert component, i. e. assuming its mass in the equilibrium sorptive gas
mixture to be the same as in the initial state prior to adsorption,
equations (4.1), (4.19-4.22) again provide 4 algebraic equations
from which the sorptive gas masses and adsorbate’s masses
can be determined. The result is

with i = 1,2) as given by (4.7), (4.24) and

Also the convention for i = 1, for i = 2) should be taken
into account.

Equations (4.25, 4.26) require again an iteration procedure for numerical
solution as they include the compressibility factor
