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.

Synthesis, Characterization, Adsorption Isotherm, and Kinetic Study of Oil Palm Trunk-Derived Activated Carbon for Tannin Removal from Aqueous Solution
TLDR
The AC synthesized using the optimum parameters were then characterized and tested as an adsorbent for tannin, and N2 sorption results revealed that the AC exhibits type IV isotherm, that is, contains micropores and mesopores and displays a relatively high BET specific surface area. Expand

Pyrolysis wastewater treatment by adsorption on biochars produced by poplar biomass.
TLDR
The study shows that higher temperature in the biochar production leads to higher sorption capacity of the organic compounds due to an increase of the surface area, and this leads to the potentiality of biochar as adsorbent material for the treatment of pyrolysis wastewater. Expand
Influence of natural organic matter on equilibrium adsorption of neutral and charged pharmaceuticals onto activated carbon.
TLDR
While reduction in surface area was similar for both preloaded GACs, up to 50% lower pharmaceutical removal was observed on wastewater preloaded NOM, indicating that NOM competition may influence pharmaceutical removal more than pore blocking. Expand
