| 摘 要： | 用等离子体质谱法同时测定地质样品中超痕量Au、Pt、Pd、Os、Ir、Ru、Rh和Re。试验了HCl／H2O2封闭溶样法，研究了ZPA4螯合树脂富集8元素的条件，并通过树脂灰化、HCl／H2O2封闭分解制备成试液，供ICP—MS测定。本法的检出限（ng/g）分别为0．21Au、0．12Pt、0．20Pd、0．024Os、0．016Ir、0．028Ru、0．022Rh、0．22Re，方法的相对标准偏差（RSD）为3．1％～14．8％。本法的特点是有效地降低了空白值，提高了仪器的检测能力。

| Abstract: | Detemination of ultratrace Au,Pt,Pd,Os,Ir,Ru,Rh,Re in geological samples by ICP-MS was described in this paper.The method of HCl/H2O2 closed tubes dissolution of minerals was tested.The condition of ZPA4 resin concentration of eight elements was studied.The solution for ICP-MS determination was prepared by resin ashing,and then HCl/H2O2 closed tubes dissolution.The detection limits(ng/g) are 0.21 for Au,0.12 for Pt,0.20 for Pd,0.024 for Os,0.016 for Ir,0.028 for Ru,0.022 for Rh,0.22 for Re.Relative standard deviations for these elements are 3.1% to 14.8%.The method effectively reduces blank value,and improves the detection ability. |
