| 摘 要： | 研究了微波消解酸溶和过氧化钠碱熔两种测定岩石样品中锆、铌、铪、钽前处理方法,利用电感耦合等离子体质谱法进行测定。对所选用不同种类的岩石国家标准物质样品进行了条件实验,结果表明:采用过氧化钠碱熔法处理岩石样品后,锆、铌、铪、钽的测量值准确度高,且相对标准偏差(RSD,n=10)小于6%,该方法更适用于岩石样品中锆、铌、铪、钽的测定。

| Abstract: | Two different sample pretreatment methods—Na2O2 fusion method and microwave digestion method were compared in determination of Zr,Nb,Hf,Ta in rocks by inductively coupled plasma-mass spectrometry.Various National Standard Reference rock samples were analyzed using the two sample pretreatment methods.The results indicate that Na2O2 fusion method provides higher accuracy and precision(<6%RSD,n=10) than microwave digestion method and is suitable for the determination of Zr,Nb,Hf,Ta in rock samples. |
