| 中文摘要: |
| 将三苯基膦氯化铑用硝酸、高氯酸消解，以混合酸溶解样品，用ICP-AES法测定三苯基膦氯化铑中的微量Al、Cu、Fe、Mg、Pd、Ni、Pb、Pt、Zn杂质元素含量。选择合适波长消除光谱干扰，用背景点扣除的方式消除铑对Fe、Ni、Pb、Pt、Zn的基体干扰。各杂质元素的检测范围为0.001%~0.1%，加标回收率为93.25%~117.0%，精密度(RSD)为0.18%~15.41%。与直流电弧发射光谱分析方法相比，准确度和精密度均得到提高，高纯铑基体消耗减少，操作简化。 |
| 英文摘要: |
| A method for the determination of Al, Cu, Fe, Mg, Pd, Ni, Pb, Pt, Zn in tris(triphenylphosphine) rhodium(I) chloride by ICP-AES was developed. The samples were digestion by HNO3 and HClO4, then dissolved with HCl+HNO3. The matrix effects come from Rh to Fe, Ni, Pb, Pt, Zn were eliminated by background point correction. The determination range is 0.001%~0.1%. The recoveries and RSD were 93.25%~117.0% and 0.18%~15.41%, respectively. Comparing with DC arc emission spectrometry, the method is more accurate and precise, less comsumption of high purity rhodium and easy to operate. |
