Abstract
A series of metal-impregnated alumina samples were prepared by the incipient wetness impregnation technique. The surface areas of the powdered samples (AL and ABET) were determined by the two most common methods, i.e. the Langmuir method and the BET method. The adsorbates used were methanol, ethanol, l-propanol and n-butanol (n-aliphatic alcohols) which were designated C1, C2, C3 and C4, respectively. It was observed that AL and ABET of the adsorbent occupied by the adsorbate molecules decreased from C1 to C4. It was also noted that the variation of AL and ABET with temperature followed exactly the same trend.
