The analysis of adsortion behaviors of some cigarett aerosol ingredients such as tar, nicotine, carbon monoxide and a number of organic acids has shown that the rates of adsorption of the adsorbates of lower boiling point had increased in accordance with increasing cumulative pore volume, while that of higher doiling point decreased with increasing pore volume of smaller radius. The adsorbents used here were charcoal, silica gel, alumina, and activated clay. The common principle that the adsorbents of greater specific surface area adsorb the larger amount of adsorbates appeared to be disturbed in the adsortion of higher boiling point adsorbates. This confirmation was made mainly by analyzing the adsorption behaviors with regard to the pore volume distributions evaluated on the bases of desorption isotherms.
