Abstract
The specific surface area determination of activated carbons by means of the low-temperature argon adsorption (the BET method) was compared with the measurement of the surface area based on the adsorption of I2 from the aqueous KI solution. It is proposed to recalculate the iodine adsorption number for the BET surface area. It is shown that the SIN method can be used for a quick estimation of the structure development of porous carbonaceous materials.
