Adsorption volume and adsorbate density

Abstract

A method is proposed for estimating adsorption volume and average adsorbate density. The
method is based on the assumption that the adsorbate density at critical temperature is equal to the
doubled critical density of the bulk liquid. Besides, calculations are made by using the experimentally
determined thermal coefficient of limiting adsorption. The method is tested for its validity by applying to
six adsorption systems.
