摘要

本文研究了30%TBP-煤油-1 mol/L HNO,3,两相混合及1 mol/L HNO,3,平衡过的30 %TBP-煤油单有机相两种条件下TBP辐解生成DBP和MBP的规律。混合相辐照TBP降解成DBP的主要过程发生在有机相中；在剂量小于2×10,5,Gy，混合相辐照有较高的DBP生成G值，而当剂量大于2×10,5, Gy时，混合相与单相辐照生成DBP的G值则趋于一致；混合相辐照MBP生成浓度比单相辐照高30%—40%。混合相辐照有较高的MBP生成浓度及低剂量下有较高的DBP生成G值，很可能与混合相中含有大量水及辐照时接触到较多的氧气有关。

Abstract

The various role of the formation of HDBP and H,2, MBP in ,γ, irradiated 30% TBP-Kerosinc-1 mol/L HNO,3, mixed phase (with a phase ratio of 0/A= 1:1) is studied. A comparative result in irradiated 30% TBP-Kerosine single organic phase has been made. It shows that in irradiated mixed phase, the major source of HDBP formation is the organic phase and the H,2,MBP concentration yielded in irradiated mixed phase is 30%-40% higher than in irradiated single phase. In addition, the HDBP G value in irradiated mixed phase is much higher than in irradiated single phase during the absorbed dose ,<,2×10,5, Gy, but when the absorbed dose ,>,2×10,5,Gy. there is no remarkable difference for it. The reason of the difference for the radiolysis of TBP in irradiated mixed phase and single phase has been discussed, the existence of much more O,2, and H,2,O in irradiated mixed phase system plays a main role.
