Abstract

The gamma-ray initiated oxidation of dicyclohexano-18-crown-6 (DCH-6) was studied in two-phase system under agitation: nitric acid, aqueous solution and organic solvent.

The distribution coefficients of radionuclides, hydrodynamic characteristics (phase separation and interface surface tension), and the radiolysis products after irradiation at a dose rate (60Co) of 1.7 Gy/s were determined. The maximum total dose was 3.O×105 Gy (3.0×107R).
