摘　　要：以TBP-萃淋树脂萃取分离基体铀,通过对发生器功率、雾化气流量、样品提升量等进行条件试验,建立了六氟化铀中杂质元素钽的ICP-AES测定方法。在取样量为250 mgU时,方法的检出限为0.60μg/gU,方法的加标回收率为86.6%~113.4%,相对标准偏差小于12%。A method was developed for detection of tantalum in uranium hexafluoride by ICP-AES, using TBP-extraction resin for the separation of matrix uranium. Optimal conditions for generator power, atomizing gas flow and enhance the amount of samples, and so on, were researched. The limit of detection of the method was 0.60 μg/gU with sampling of 250 mgU.The recoveries were 86.6%~113.4%, and the relative standard deviations were less than 12%.
