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.
