摘要
对于大量化探样品的测定 ,方法必须尽量操作简便、程序快捷、成本经济和结果可靠。本方法采用酸溶分解样品 ,活性炭吸附分离富集Au、Pt、Pd ,结合电感耦合等离子体发射光谱法进行测定 ,方法的检出限为 0 2ng/g(Au、Pd )～ 0 5ng/g(Pt) ,用于化探样品的测定 ,结果与推荐值吻合较好 ,5次平行测定的RSD在 6 5 %～ 1 3 5 %。方法简便快速 。
The preconcentration and determination of trace Au,Pt,Pd in geological materials by active carbon and ICP-AES were described in present paper.The operating conditions of the instrument and method were optimized.The interferences from common coexistent elements were studied.Three elements can be collected and determined simultaneously.The detection limits(ng/g)are 0 2 for Au and Pd,0 5 for Pt.The method has been applied to the determination of Au,Pt and Pd in geological materials with satisfactory results.
