| 中文摘要: |
| 采用盐酸-过氧化氢微波消解铑粉样品，动态反应池(DRC)技术消除复合离子对Fe、Si的干扰，以内标校正法克服基体效应，建立了电感耦合等离子体质谱法(ICP-MS)测定纯铑中Mg、Al、Si、Mn、Fe、Ni、Cu、Zn、Ru、Ag、Pd、Sn、Ir、Pt、Au和Pb共16个杂质元素含量的方法。以Y、Re、Sc和In为内标元素，测定加标回收率为88.5%~116.2%，精密度(RSD)为0.63%~13.44%；方法测定下限低，除Fe(0.0001%)和Si(0.0005%)外，其余元素测定下限均不高于0.00005%，在无高纯铑基体匹配的条件下，可满足99.99%的高纯铑测定要求。 |
| 英文摘要: |
| An analytical method was proposed for the determination of 16 impurities in pure rhodium by inductively coupled plasma mass spectrometry (ICP-MS). These impurities include Mg, Al, Si, Mn, Fe, Ni, Cu, Zn, Ru, Ag, Pd, Sn, Ir, Pt, Au and Pb. Rhodium samples to be tested was digested by a mixture of HCl and H2O2 in microwave oven. The interference of multifunctional ions to Fe and Si was eliminated by the dynamic reaction cell technology (DRC). Y, Re, Sc and In were used as internal elements for the 16 impurities. The recoveries and precision (RSD) were measured to be 88.5%~116.2% and 0.63%~13.44%, respectively. Detection limit was 0.0001% for Fe, 0.0005% for Si and 0.00005% for other elements. The method can be applied to the analysis of 99.99% high-purity rhodium, in case of no rhodium matrix matching available. |
