Tritium incorporation into functional materials by applying OT-for-OH exchange reaction

In order to reveal (1) the behavior of the tritium-labeled hydroxyl group ( i.e., OT group) and (2) the effect of temperature on the dissociation equil ibrium of tritiated water, the OT-for-OH exchange reaction in a homogeneous system was observed (1) using ion-exchange resins and HTO water, and (2) u sing hydrogen oxides and HTO water. Consequently, the following four conclu sions were obtained: (1) The OT-for-OH exchange reaction occurred between e ach anion-exchange resin (or each metal hydroxide) and HTO water. (2) The h igher the temperature is, the smaller the activity of both anion-exchange r esin and metal hydroxide will be, and the activity of cation-exchange resin is large when the temperature is high. (3) The larger the degree of crossl inking in each Biorad AG1 resin is, the lower the activity of the resin wil l be. (4) The exchange rate for the OT-for-OH exchange reaction is small wh en the electronegativity of the metal ion in the metal hydroxide is large.
