摘　　要：混合三烷基氧化膦 (TRPO)是一种优良的镧系元素和锕系元素萃取剂 ,已用于高放废液的α核素的萃取分离。本文用傅里叶红外光谱法研究γ辐照的 30 % TRPO-煤油 -HNO3 体系的辐照稳定性 ,结果显示 ,该萃取剂对放射性辐射是稳定的 ,主要的辐解产物是硝基烷和羧酸。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.
