Description
The behavior of hydrophobic catalyst supports in the isotopic exchange reactions H/D/T was analyzed by determination of radiolytic processes in presence of tritiated water. In this study the behaviour of polytetrafluoroethylene and styrene-divinyl benzene copolymer catalyst supports in presence of tritiated water was analyzed. Radiolytic effects were evaluated using quantum-chemical methods. The primary and secondary radiolytic effects were evaluated using an original model. Radiolytic processes were analyzed too by exposure at gamma radiation emitted by a 60Co source of catalytic supports immersed in water and analysis of chemical modification by IR spectroscopy, and flouride emission, in case of PTFE.
