| 摘 要： | 采用氢氟酸-硝酸-高氯酸体系对华阳川铀多金属矿进行高温消解,并对消解条件进行优化,建立了电感耦合等离子体发射光谱(ICP-OES)法对华阳川铀多金属矿中铌和铅元素进行测定的方法。结果表明,方法线性相关系数分别为0.9998和0.9999,两种元素在标准样品中的加标回收率为96.0%~104%,平行样的相对标准偏差为0.50%~3.3%。实际样品加标回收率为96.1%~102%。方法快速、准确。

| Abstract: | Huayangchuan uranium polymetallic ore was digested at high-temperature by HF-HNO3-HClO4 system under the best digestion conditions.Nb and Pd elements in huayangchuan uranium polymetallic ore were detected by inductively coupled plasma atomic emission spectrometer(ICP-OES)under the best instrumental conditions.The results show that the linear correlation coefficient of the method is 0.9998 and 0.9999 respectively,the recovery of Nb and Pd in the standard samples is between 96.0%and 104%,and the relative standard deviation(RSD)of the parallel samples is about 0.50%to 3.3%.The recoveries of the actual samples are about 96.1%—102%.The analytical test method can be used for the rapid and accurate determination of Nb and Pd in Huayangchuan uranium polymetallic ore. |
