  • Can coal based activated carbon remove iodine?
  • The both above-mentioned test results show: The decontamination factor of the coal-based activated carbon for removing stable iodine is more than 1000, and the iodine removal efficiency can reach above 99.9%, which could meet the demand of removing iodine from the gaseous waste of nuclear powered vessel and other nuclear plants.
  • Does activated carbon have a high specific surface area and iodine adsorption performance?
  • Previous studies have shown that activated carbon prepared under these conditions has a high specific surface area (334.27 m 2 ·g −1) and iodine value (536.26 mg·g−1) and shows a relatively developed pore structure and iodine adsorption performance [ 21 ].
  • Which factors affect the iodine value of activated carbon?
  • In other words, this indicates that the activation time has the greatest influence on the iodine value of activated carbon, followed by the heating rate and carbonization temperature, while the activator type has the least influence on the iodine value of activated carbon. Table 4. Range analysis of factors that affect the iodine value.
  • Does the iodine value of activated carbon reflect the s bet total?
  • The iodine value of activated carbon has a good linear relationship with S BET, total, which indicates that the iodine value can well reflect the S BET, total of activated carbon. Fig. 8 b presents the research results of Saka [ 36 ], which also show that the iodine value and S BET, total have a good linear relationship.
