| 中文摘要 | 采用液体闪烁法测定硅胶相中负载的Pu,研究样品制备条件和测量参数等对分析结果的影响。在闪烁瓶中加入少于1g负载Pu的干硅胶和10mL闪烁液,搅拌5min,用液体闪烁计数器测量300～800道窗口范围内的计数,可得到Pu的α活度。实验研究了HNO_3、Fe、Zr、Nd等杂质对液闪测量的影响,并对液闪测量谱图进行了初步解析。; The liquid scintillation counting analyzer is used to determine theα-activity of Pu adsorbed in silica gel.The influences of preparation conditions and measuring param- eters were studied.In order to determine the a-activity of Pu in silica phase,less than 1 g of silica gel was added into a 20 mL scintillation vial with 10 mL of cocktail.After 5 min of stirring,samples were measured by liquid scintillation analyzer.The activity of Pu in the vial equals to the total counts in energy window of 300-800 channel.The influ- ences of HNO_3,Fe,Zr,Nd on Pu analysis were studied.The formation of spectrogram was also preliminarily analyzed. |
