DT—1016型阴离子交换树脂分离富集金铂钯

Separation and Preconcentration of Gold,Platinum and Palladium in Geological Samples with DT-1016 Anion Exchange Resin

  • 摘要: 研究了DT-1016型阴离子交换树脂对超痕量Au,Pt,Pd的吸附性能及条件。在0.025mol/L HCl介质中,流出速度为0.5-1.0mL/min时,Au,Pt和Pd的富集效果最佳,吸附率分别为99.72%,99.06%和97.95%,共存离子无显著性影响。用等离子体质谱测定标准物质中Au,Pt和Pd,其结果与标准值基本相符。检出限Au为0.27μg/L,Pt为0.40μg/L,Pd为0.19μg/L。对GBW 07294铂族元素国家标准物质进行精密度试验,RSD(n=8)Au为19.2%,Pt为
