中文摘要: 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。使用电感耦合高频等离子体原子发射光谱仪(ICP-OES),在最佳仪器条件下,对华阳川铀多金属矿中铌元素和铅元素进行检测。结果表明,方法线性相关系数为分别为0.9998和0.9999,两种元素在标准样品中的加标回收率在96.0% ~104% 之间,平行样的相对标准偏差约0.50%~3.32%。实际样品加标回收率约为96.1 % ~ 102 %。该分析测试方法可以对华阳川铀多金属矿中铌铅元素进行快速、准确的测定。
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 3.32%. 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.
