NK8310螯合树脂分离富集地质样品中痕量金银铂钯及其测定

Determination of Trace Gold, Silver, Platinum, Palladium in Geological Samples by AAS after Separation and Preconcentration of These Elements with NK8310 Chelate Resin

  • 摘要: 研究了硫脲螯合树脂(NK8310)分类富集地质样品中痕量Au、Ag、Pt和Pd的实验条件。在φ=10%的王水介质中,AuCI4^-、AgCI2^-、PtCI6^2-和PdCI4^2-定量吸附于树脂上并与大量贱金属分离;用5g/L硫脲-0.12mol/L HCI溶液洗脱Au、Ag、Pt和Pd,回收率为97%-104%。用硫镍矿管理样以及国家一级标准物质进行分析验证,分析结果与推荐值及标准值吻合,表明NK8310螯合树脂适用于地质样品中Au、Ag、Pt和Pd的分离富集。
