Abstract
The construction of a low-cost apparatus for gas adsorption on solids and prior heat treatment of the adsorbent are discussed. The equilibrium pressure of the gas in a calibrated volume at a constant temperature is related to the extent of the gas adsorption. By means of the adsorption results, the solid surface-area calculation is performed using both BET and Langmuir isotherms. This apparatus provides surface-area values in good agreement with both values obtained by a commercial instrument and those reported in the literature, within the experimental error.
