Abstract

The effects of temperature, H2O2, and reuses on the performance of activated carbon for the decontamination of dilute tritiated water were investigated. The effects of these factors on the selective separation of HTO were divided into positive or negative aspects, and the effects were analyzed using the maximum partition coefficient. The increase in temperature had a negative effect on the selective separation, but the addition of H2O2 had a positive effect. Additionally, the reuse of activated carbon also had a negative effect, but it maintained a performance similar to that of fresh carbon until it was reused three times.
