研究了样品溶解和仪器测定的最佳工作条件,通过选择铬、镍元素的灵敏线为分析线,在高低标溶液中加入与样品同量的基体元素消除基体的影响,实现了用电感耦合等离子体-原子发射光谱法测定钴基钎料中铬和镍。样品加标回收率在97.5%—103.5%,用于标准样品中镍、铬的测定,标准样品测定结果与标准值相符,标准样品测定值的相对偏差在±0.80%以内。
The optimum working conditions of sample dissolution and instrument determination were studied. By selecting the sensitive lines of chromium and nickel as the analytical lines, the same amount of matrix elements as the samples were added to the high and low standard solutions to eliminate the influence of the matrix, and the inductive coupling Determination of Chromium and Nickel in Cobalt Based Solder by Plasma - Atomic Emission Spectrometry. The recoveries of spiked samples ranged from 97.5% -103.5% for the determination of nickel and chromium in standard samples. The results of standard samples were in accordance with the standard values, and the relative standard deviations of the standard samples were within ± 0.80%.
