ABSTRACT = {This study introduced a significantly effective approach called the
microwave-enhanced Fenton method to degrade spent radioactive cation
exchange resin. Compared with the Fenton (99% after 180 min) and photo-Fenton
(90% after 198 min) reactions, this unique microwave-enhanced Fenton reaction
has the highest degradation rate for spent radioactive cation exchange resin degradation (98.55% after 60 min). Carbon dioxide, sulfate and small molecular compounds were produced in the degradation of cation exchange resin, as determined
by XRD and FT-IR. A model for the microwave-enhanced Fenton degradation
mechanism of cation exchange resin was constructed. Microwaves were implemented to boost the concentration of hydroxyl radicals in the Fenton reaction so that the
cation resin infiltrated and formed a channel to facilitate entrance of hydroxyl
groups into the interior of the resin. This paper provides a method for accelerating
the treatment of spent radioactive ion exchange resin, which could exert a signifi-
cant influence on the degradation pathway for radioactive organic matter.},
