DETERMINATION OF THE POSITION OF THE INITIAL POINT OF THE HYSTERESIS LOOP IN A MODEL OF CYLINDRICAL PORES

An equation containing a correction for the structural characteristics of the adsorbents and adsorbates was proposed for the determination of the coordinates of the initial point of the hysteresis loop on the adsorption isotherms of the vapor of various types of compounds. The applicability of the equation to four different adsorption systems was tested by comparing the calculated results with data determined from the isotherm.
