摘　　要：用高分 辨率 毛细 管气 相色 谱法及 等离 子体 光谱 法研 究了核 工业 领域 应用 的萃 取剂 三烷基 氧化 膦（ Ｔ Ｒ Ｐ Ｏ）酸性含磷 辐解产物。研究表明，在 γ辐照条件下酸性辐解产 物主要为二烷基膦酸、一烷基膦酸，磷酸及脂肪酸。其产额分别为 ０．５８、０．０６７、０．０１４ 及 ０．５６。In this paper, radiolytic products of trialkyl phosphine oxide kerosene solution by γ ray irradiation have been investigated by gas chromatography.Experimental results show that main radiolytic products were phosphinic acid (R 1R 2POOH),phosphonic acid[RPO(OH) 2],phosphoric acid (H 3PO 4) and caboxylic acid.Determination of phosphoric acid is carried out by ICP AES,other by gas chromatography.The acid yield (G Value) of R 1R 2POOH , RPO(OH) 2 , H 3PO 4 and carboxylic are 0.58, 0.067,0.014 and 0.56,respectively. The radiolytic link of TRPO could be described as: TRPO→R 1R 2POOH→RPO(OH) 2→H 3PO 4
