Conclusions

  1. 1.

    Methods have been developed for studying the dynamics for the adsorption of vapors of highly volatile substances by industrial sorbents, using gas-chromatographic apparatus.

  2. 2.

    Under conditions of a dry vapor-air flow and charge, AU-3 type of activated carbons have the greatest dynamic activity with respect to ethyl chloride vapor. For moist air and uniformly moistened charge, the sorbents having highest value of the constant B in the adsorption equation from the theory of the bulk micropore filling have a better dynamic activity.

  3. 3.

    The features noted in experiments with readily adsorbed substances (benzene) are characteristic of the adsorption dynamics of C2H5Cl vapor in the region of low breakthrough concentrations.
