摘要： 本文研究N,N-二正丙基丁酰胺(DPBA)对辐照磷酸三丁酯(TBP)的保护作用, 实验发现在~(60)Coγ辐照下, 它对TBP~*。具有双重能量转移效应, DPBA本身辐解, 属于“自我牺牲”机理。应用稳态原理得出辐解TBP的两种激发态分子的能量抑制方程。
Abstract: 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 undergoes 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:....
