Free radical oxidation of spent radioactive organic solvent

The decomposition of radioactive Spent Organic Solvent (SOS) was conducted successfully in bench scale tests. The experiment results showed that TBP/OK can be decomposed under with in H 2O 2 Fe 2+ /TiO 2 H 2SO 4 systems under suitable H 2O 2 concentration, catalyst, temperature and pH. The free radical oxidation reaction mechanism using H 2O 2 under the action of the synergistic catalysis TiO 2/Fe 2+ was also discussed briefly.

Experimental Study on Conditioning of Spent Organic Solvent (TBP/OK)

Spent Organic Solvent (SOS),TBP/OK is one of the low and intermediate level liquid radioactive wastes generated in nuclear facilities. This paper studies the decomposition behavior of SOS in H2O2-Fe2+/TiO2-H2SO4 systems and analyzes the effects of such factors ad H2O2 concentration,catalysts,temperature adn pH on the reaction process. The physical and chemical characteristics of the reaction condensate and decomposition residual from preliminary experimental results are also described. The chemical oxidation reaction mechanism using H2O2 under the action of the synergetic catalysis TiO2/Fe2+ is also discussed briefly.
