Abstract: Some general relationships expressing the shape of adsorption isoplane
and the height of adsorption zone have been deduced under supposition that
the mass-transfer coefficient in solid phase is not constant during saturation.
An analytical expression giving the dependence of mass-transfer coefficient
in solid phase on concentration of adsorbate in adsorbent has been presented.
This expression is valid on condition that the adsorption equilibria in
a system may be described by the Langmuir equation of adsorption isotherm.
On this basis the equations of adsorption isoplanes have been expressed
for the validity region of the Langmuir equation of adsorption isotherm.
