| Abstract: | The mixed trialkyl phosphine oxide (TRPO) is an excellent extractant for removing actinides and lanthanides from high level radioactive waste solution.Radiolytic products of gamma irradiated 30% TRPO kerosene HNO 3 were studied by FT IR spectrometry.The results showed that radiolytic products of TRPO were nitro compounds and carboxylic acid.The PO peak(1166cm -1 ) and CH peak of irradiated and not irradiated TRPO were same.It showed the extractant TRPO is stable to radioactive radiation. |
