Abstract
State-of-the-art analysis for oxidizing technologies related to destruction of complexons and metalloorganic complexes in
 liquid radioactive waste has been carried out. Ways already put into practice, as well as the experimental ones have been
 considered. Oxidation by potassium permanganate and hydrogen peroxide and also ozonization and photo oxidation have
 been considered in detail. It has been shown that oxidation by potassium permanganate with subsequent filtration leads to
 decrease of isotopes activity, but hereby a considerable volume of manganese dioxide is formed. The ozonization application
 allows reduce considerably the liquid radioactive waste (LRW) volume, but along with this ozone is the extremely toxic and
 explosive substance demanding a special equipment for its production. Efficiency of oxidation by hydrogen peroxide and photo
 oxidation without catalysts is low. The special attention has been paid to combined oxidizing methods (AOP) based on use of
 ultra-violet (UV) radiation together with ozone and/or hydrogen peroxide. Such methods allow apply the strongest oxidizer –
 hydroxyl radical – for LRW processing. Efficiency of AOP-methods and their technological capabilities are substantially defined
 by characteristics of used UV radiation sources. A detailed analysis for a wide range of UV radiation possible sources (low
 and average pressure mercury lamps, amalgamate lamps, excimer lamps, light-emitting diodes and pulse xenon lamps) has
 been carried out, their comparative assessment has been executed. Great potential opportunities for the pulse xenon lamps
 providing a continuous range of radiation in UV area and high intensity for a stream of high-vigorous photons have been noted.
