NEW EQUATION OF ADSORPTION FOR THE CALCULATION OF PARAMETERS OF MICROPOROUS STRUCTURE

A new equation describing the equilibrium adsorption of vapors of subs tances with different physicochemical properties was obtained on the b asis of the lognormal distribution of pore volume within the theory of volume filling of micropores. Unlike the existing equations, this equ ation is more general since it is not related to a specific geometrica l model of pores. Adsorption isotherms described by this equation for active carbons with wide pore-size distributions have smaller mean squ are deviations than those calculated using the Dubinin-Stoeckli equati on.
