Conclusions

  1. 1.

    We have obtained exact analytical expressions for the kinetic curves and for local sorbate concentration distribution in a spherical granule of biporous sorbent with linear sorption isotherms and an exponential kinetic function of the micropore zones.

     
  2. 2.

    We have analyzed the conditions under which it is possible to determine the characteristic diffusion relaxation times in the transport pores and the micropore zones from the first two moments of the experimental kinetic curves.

     
  3. 3.

    These theoretical expressions can be used to interpret tests of sorption kinetics on granulated zeolites, ion exchangers, and two-phase polymers (block copolymers).
