【摘要】 采用含N、S功能团的螯合树脂YPA₄富集铂族元素和金。Au、Pt、Pd、Os的吸附率为98％以上,Ir为92％,Ru为90％,Rh为87％。把树脂灰化,用激光将其灰份气化输入等离子体激发,光谱测定。取样5g时,可测定0.2ng/g的Au,0.6ng/g的Os、Ir,0.06ng/g的Pt、Pd、Rh、Ru。标样分析结果与标准植吻合。更多还原

【Abstract】 The separation and preconcentration of platinum group elements and gold with YPA4 chelating resin are described. The adsorption ratio on this resin is 98%-100% for Au, Pt, Pd, Os, 92% for Ir, 90% for Ru, and 87% for Rh, respectively. The resin is treated by high temperature furnace. It is vaporized by continuous laser and introduced in to ICP. Te detection limits are 0. 06 ng/g for Pt, Pd, Ru, Rh, 0. 2 ng/g for Au, and 0.6ng/g for Os, Ir, respectively. The results obtained are in agreement with the recommended values of Standard reference materials.更多还原
