从水溶液中萃取铀时非常广泛地采用溶于不同稀释剂中的 TBP。测定 TBP 中的铀通常要将铀反萃取到水相中或破坏 TBP 有机物后才能进行。这对于分析高放样品是费时的并且很不方便,因为需要附加设备以防止放射性沾污。此外用反萃或坏破有机物的方法其测定准确度也不如直接滴定法高。戴维斯和格雷曾提出过滴定分析测定铀的方法,该法在纽布鲁斯维克实验室(NBL)得到了验证,分析了大量不同类型的铀燃料样品。据报道,当水溶液中存在的 TBP 较少时,用该
TBP dissolved in different diluents is very widely used to extract uranium from aqueous solutions. Determination of uranium in TBP is usually carried out after the uranium is back-extracted into the water phase or destroyed TBP organics. This is time consuming and inconvenient for analyzing high-sample release as additional equipment is required to prevent radioactive contamination. In addition the method of using stripping or broken broken organism, the determination accuracy is not as high as the direct titration method. Davis and Gray have proposed a method for titrimetric determination of uranium, validated at the New Brunswick Laboratory (NBL), analyzing a large number of different types of uranium fuel samples. It has been reported that when there is a small amount of TBP present in the aqueous solution, it is used
