摘要
建立了SP-3580型原子吸收分光光度计火焰法测定固体三氯化钌中铁含量的实验方法。通过对样品溶解条件和测定条件进行优化,确定了SP-3580型原子吸收分光光度计测定固体三氯化钌中铁含量的最佳分析操作条件。方法精密度(RSD)为3.25%~3.94%,加标回收率为94.0%~103.3%。结果表明,该方法具有准确度高,重复性好等特点,能够满足实际生产中固体三氯化钌产品杂质铁元素的分析检测要求。
The flame atomic absorption spectrophptometry method was used to determine iron content in solid ruthenium trichloride by SP-3580 atomic absorption spectrometry. The dissolution conditions and the measuring conditions were optimized, then the optimal analytical conditions were determined. The RSD was 3.25%~3.94% and the recovery of standard addition was 94.0%~103.3%. The method had advantages of high accuracy and good reproducibility, and it can meet the requirement of iron determination in ruthenium trichloride product.
