摘要
X—射线荧光光谱中,直接压饼或四硼酸锂熔饼法,具有简便、快速的优点,但测定~10ppm以下含量的稀土元素是相当困难的。用离子交换纸制样,X—射线荧光光谱测定稀土元素及钪,可降低检测限至0.xppm,甚至更低。与中子活化法,同位素稀释质谱法相比,本法价廉、方便、快速。与国内同类方法相比,本法取样少,分析周期短,易掌握。
A rapid and selective X-Ray fluorescence spectrometric method for determination of trace amounts of REE in ores is described.It is based on the pre-concentration with ion-exchange paper.Beer’s law is obeyed for REE of 0-100ppm.The detection limit is 0.x ppm.The results obtained are in good agreement with those obtained by isotopic dilution measurement and neutron activation analysis.
