| 摘 要： | 近年来,着地质学科的研究需要,稀土元素的分析手段不断向深度发展。为了制作稀土球粒陨石标准化分布型武图,要求准确测定痕量稀土元素,同时还由于各种岩石的基体变化不一,造岩元素所产生的谱线干扰以及可变的背景干扰都给痕量稀土元素的测定带来困难,所以,一般都需要进行预处理,将岩石的主元素分离,并使稀土元素相对浓缩。

THE SIMULTANEOUS DETERMINATION OF 15 TRACE RARE EARTFI ELEMENTS IN ROCKS BY PLASMA ATOMCOMP DIRECT READING SPECTROMETER SYSTEM |
| |
| Abstract: | A method for the determination of rare earth elements at chondritic
abundance levels is described. Dissolution of rock samples is accomplished
by sodium peroxide fusion. Rare earth elements are separated from matrix
concomitants and pzeconcentrated by canon exchange employing No. 1 resin.
The analysis of the samples is performed on a Jarrell-Ash model 1160 Atom-
Comp spectrometer with 60 channels. A DEC PDP 11/23 minicomputer controls
the ICAP spectrometer and is interfaced to a LA-120 DECwriter for data
reporting. A precision of 1-5.5%(RSD) was attained. Analyses of several hun-
dreds of rock samples showed that the method is well suited to the routine
simultaneous determination of 15 rare earth elements. |
