Water adsorption and micropore structure of carbon adsorbents. 2. Graphical analytical method of determining the parameters of the Dubinin-Serpinskii adsorption isotherm equation and its application

Abstract

1. We have studied adsorption isotherms of benzene vapor and water vapor on activated carbons with both narrow and relatively wide micropore volume distributions by size. 2. We have proposed a graphical method of determining the parameters of the Dubinin-Serpinskii water adsorption isotherm equation (DS-2). 3. Good agreement has been found between experimental water-vapor adsorption isotherms and those calculated by Eq. DS-2 run on activated carbons in the relative pressure range between 0.1 and 1.
