Radiolyis of polytetrafluoroethylene and polystyrene catalytic supports in presence of tritiated water

The behavior of hydrophobic catalyst supports in the isotopic exchange reactions H/D/T was analyzed by the determination of radiolysis processes in the presence of HTO. In this study, the behavior of polytetrafluoroethylene and styrenedivynilbenzene copolymer catalyst supports in the presence of HTO was analyzed. The primary and secondary radiolytic effects were evaluated using original computational methods. The radiolytical processes were analyzed by exposure of the catalytic supports immersed in water to gamma radiation, and also by analysis of chemical modification by FTIR spectroscopy, fluoride formation and sol/gel fraction determination.
