随着地质科学研究的深入,发现稀土元素的配分能提供一系列有价值的数据,用于确定岩浆来源,判断岩体与矿床的成因关系,论证岩体与岩系是否同源,再现岩浆演化情况及了解岩浆演化过程中的氧化,还原条件等等比利用其它微量元素精确、可靠。为了满足地质研究工作的需要,迫切需要制定岩石及矿物中痕量稀土元素的分析方法。 由于原子发射光谱分析法具有同时测定多元素的优越性,早在稀土元素分析工作中占了极重要的地位,电感耦合等离子体光源的发展更提供了进一步提高其测定灵敏度及准确度的途径。
With the deepening of geological science research, it was found that the distribution of rare earth elements can provide a series of valuable data for determining the source of magma, determining the genesis relationship between the rock mass and the deposit, demonstrating whether the rock mass and the rock series are homologous, and reproducing the magmatic evolution Situation and understanding of the magma evolution process of oxidation, reduction conditions, etc. than the use of other trace elements accurate and reliable. In order to meet the needs of geological research work, there is an urgent need to develop methods for the analysis of trace amounts of rare earth elements in rocks and minerals. Due to the advantages of simultaneous determination of multiple elements by atomic emission spectrometry, it has played an extremely important role in the analysis of rare earth elements as early as possible. The development of inductively coupled plasma light sources further provides a way to further improve its sensitivity and accuracy.
