N,N-dialkyl substituted alkyl amide has been shown as the extractant for the extraction and separation of actinides in a Purex-type flowsheet since its synthetizing is cheap enough.It exhibits a similar behavior as tri-n-butyl phosphate (TBP) but it has better decontamination of uramium from some fission products, better uranium-thorium separation, higher stability and under es to lessdeterious degradation products than TBP~[1-3].
The kinetics and mechanism of energy transfer in TBP-DPBA system have been studied and two-fold protective effect on excited TBP has been found. By using the principle of steady state, the energy transfer equation of the first kind of excited TBP is derived as follows:
