Iodine-doped activated carbon fibers (ACFs) were prepared by the iodine immersion method on pitch-based ACF. Then iodine-doped ACFs were heated in argon at 523 K for 4 h and at 673 K for 2 h. The iodine structure of the resultant iodine-doped ACFs was examined using X-ray photoelectron spectroscopy.
Whereas the amount of cyclodextrin (CD) adsorbed onto the large-pore activated carbon A (AC-A) increased with the number of glucose units, the amount adsorbed onto the small-pore activated carbon B (AC-B) showed the opposite tendency. This behavior can be accounted for in terms of a molecular exclus
## An investi~atjon was made on the adsorption hehaviour of activated carbons in KI aqueous solution containing very small amounts of j2. Among the major solutes in the solution, I-, f; and I:, only IL was found to be adsorbed on the carbon. The amount of the solute for a given activated carbon wa
