A method named as "volume-expanding and pressure-reducing adsorption" is proposed. It can be usedto measure the isotherms under supercritical condition. The adsorption isotherms of phenol on activated carbonsand polymeric adsorbents are estimated and compared respectively for the systems of "phenol-activated carbon-supercritical fluid CO2" and "phenol-polymeric adsorbent-supercritical fluid CO2". The results show that theamount of phenol adsorbed on the activated carbons and the polymeric adsorbents under the supercritical conditionis much less than that under the general condition, which can be utilized to develop a technology regenerating theactivated carbon with supercritical fluid. Moreover, the effects of ethyl alcohol, used as the third component, on theisotherms of phenol on the activated carbons and polymeric adsorbents under the supercritical condition are alsoinvestigated.
