The total pore volume of activated carbon is calculated by measuring the true density and particle density of activated carbon; The determination of specific surface area is based on the adsorption isotherm data within the relative pressure range of 0.05~0.35, and the BET equation is used to calculate the adsorption capacity of the single molecular layer of the sample. Based on the cross-sectional area of the adsorbate molecules, the specific surface area of the activated carbon sample is calculated. Pore volume and specific surface area are important indicators for characterizing the adsorption performance of activated carbon.
