摘要
在10％的王水介质中,采用717阴离子交换树脂交换富集Pt、Pd和Au,与大部分阳离子分离,被吸附的Pt、Pd和Au用硫脲解脱后以无火焰石墨炉原子吸收法进行测定。方法简便、快速,检测限低。各元素的特征量分别为Pt5.8γ×10^(-11)g,Pd8.9×10^(-12)g,Au7.72×10^(-12)g。方法已成功地用于岩石矿物中痕量Pt、Pd、Au的测定。
A method for determination of trace amounts of Pt, Pd and Au simultaneously in the same sample aliquot by graphite furnace AAS was described. The above elements were separated and concentrated on 717 anion exchange resin column and eluted by thioura. The characteristic mass of the elements is Pt 5.87×10-11g, Pd 8.9×10-12g and 7.72×10-12g respectively. The method has been successfully applied to the analysis of rocks.
