Conclusions

  1. 1.

    An analytical solution has been obtained for the passage of the sorbed substance through a membrane of a biporous sorbent for the case of constant concentration differences of the sorptive on its boundaries and a linear sorption isotherm.

     
  2. 2.

    The distribution of the sorptive concentration in the membrane in different moments of time has been calculated as an example, for the case of equal characteristics of diffusion relaxation times in the transporting porous system and in the microporous zones.
