Conclusions

  1. 1.

    The formation of a water monolayer in activated carbons with a uniform micropore structure takes place at a relative pressure of 0.6 independently of their porosity.

  2. 2.

    A method is proposed for the evaluation of the geometric surface area, micropore volume, and micropore linear dimensions based on a crack-shaped model with two water-vapor adsorption isotherm points corresponding to the relative pressures 0.6 and 1.0.
