| 中文摘要: |
| 采用HNO3-HClO4消解样品除碘，王水溶解铑，以钇为内标，ICP-AES准确测定碘化铑中的铑含量。考察了样品消解处理和测定的最佳条件，并与硝酸六氨合钴重量法进行了比较，两者测定结果基本相符。方法精密度(RSD)<1%(n=11)，加标回收率99.00%~101.14%。方法快速、简便。 |
| 英文摘要: |
| An accurate quantitative analysis method of rhodium in rhodium iodide with inductively coupled plasma-atomic emission spectrometry (ICP-AES) was established. The sample, after the oxidation removal of iodine with HNO3-HClO4 and dissolving by aqua regia, was determined by ICP-AES using yttrium as an internal standard. The relative standard deviations (RSD) of the method was <1%(n=11) and the recovery was between 99.00%~101.14%. The method is accurate, rapid and simple compared with the classic hexaammine cobalt nitrate gravimetriy. |
