Abstract

Dihexyloctanamide(DHOA) was used as an extractant or phase modifier with the diamide extractants in asolvent extraction process for a radioactive liquid waste treatment. The degradation compounds of the DHOAextractant, irradiated with 60Co gamma ray, were octanoic acid and dihexylamine which are identified by a Fouriertransform infrared(FT-IR) and gas chromatograph/mass spectrometer(GC/MS) analysis, and determined by theGC/MS with selected ion monitoring(SIM) mode. Retention behavior of octanoic acid, tridecane (internal standard)and dihexylamine in total ion chromatogram (TIC) were 8.65 min., 9.79 min., and 10.27 min., respectively. Withincreasing the absorbed dose of the -ray irradiated DHOA, the concentration of octanoic acid was decreased andthat of dihexylamine was increased.
