“…Adsorption onto carbon whose surface is hydrophobic is mainly based on the London dispersion force which is part of the van der Waals force. The more closely the adsorbate molecules in the pores are located to the surrounding pore walls, the higher will be the adsorption force (7). It was considered that the activation temperature increased the iodine adsorption capacity, increased the adorption force, and decreased the 1/N constant .…”
