Abstract
A new equation describing the equilibrium adsorption of vapors of substances with different physicochemical properties was obtained on the basis of the lognormal distribution of pore volume within the theory of volume filling of micropores. Unlike the existing equations, this equation is more general since it is not related to a specific geometrical model of pores. Adsorption isotherms described by this equation for active carbons with wide pore-size distributions have smaller mean square deviations than those calculated using the Dubinin-Stoeckli equation.
