| 摘 要： | 采用717阴离子交换树脂-活性炭分离富集矿石中的微量Au、Pt、Pd。40μg待测元素富集结果表明,Au、Pt、Pd的回收率分别为100%、95.3%和96.3%。以HC l为介质在无火焰原子吸收仪上测定。方法经对国家一级标准物质GBW 07291、GBW 07292分析检验,结果与标准值相符。对GBW 07291国家一级标准物质测定7次,其精密度(RSD)分别为:Au 9.4%、Pt 11.2%、Pd 3.0%。方法适用于矿石中10-6~10-9量级Au、Pt、Pd的测定。

| Abstract: | A method for the determination of gold,platinum, palladium in ores is developed.In the medium of HCl,gold,platinum,palladium is determined by graphite furnace AAS after pre-concentration with anion exchange resin and activated charcoal.The method has been applied to the determination of gold,platinum,palladium in national standard reference samples(GBW 07291 and GBW 07292).The results are in agreement with the certified values with precision(n=7) of 9.4% RSD for Au,11.2% RSD for Pt and 3.0% RSD for Pd.The method is suitable for the determination of gold,platinum,palladium in ores with concentration range of 10~(-6)~10~(-9). |
