| 中文摘要: |
| 建立了电感耦合等离子体发射光谱法(ICP-OES)测定锑精矿中10种微量元素Zn、Cd、Pb、Si、Mn、Fe、Mg、Ca、Cu、Ag的快速定量分析方法.探讨了锑精矿的溶样方法,发现采用氢溴酸挥锑后用浓酸溶解样品,稳定性较好.优化了仪器参数条件,对样品中各元素做加标回收试验.与原子吸收光谱法测定比较,方法检出限低,精密度(RSD,n=11)均小于6%,回收率为89.4%～108.0%,能满足进出口对锑精矿中杂质元素的检测要求. |
| 英文摘要: |
| A method for the determination of micro-amount of Zn, Cd, Pb, Si, Mn, Fe, Mg, Ca, Cu and Ag in antimony concenrtates by inductively coupled plasma optical emission spectrometry (ICP OES) was developed. The sample was dissolved with concentrated HCl after removing antimony by hydrobromic acid. The instrument operation parameters were optimized. The recovery of the method for these elements were 89.4%～108.0% with precision of less than 6%RSD (n=11). Compared with AAS, the method provides advantages of low detection limits, good precision, high analytical efficiency. The method is suitable for entry exit inspection of antimony concentrates. |
