摘　　要：用电感耦合等离子体发射光谱法(ICP-OES)测定氨基磺酸镍中微量铁杂质的含量,通过选择适宜的分析谱线消除光谱的干扰,并对测定条件及工作参数进行了研究。与现行的国家标准(GB/T23847一2017)方法(乙酸乙酯萃取富集比色法)相比,ICP-OES法不用萃取富集,测试步骤简单、速率快、精密度高,相对标准偏差为4.85%~6.40%,回收率为85.6%~108.8%。The content of trace iron impurities in nickel sulfamate was determined by inductively coupled plasma atomic emission spectrometry(ICP-OES).The spectral interference was eliminated by selecting appropriate analytical spectral lines,and the determination conditions and working parameters were studied.Compared with the current national standard(GB/T 23847-2017)method(ethyl acetate extraction and enrichment colorimetry),ICP-OES method does not require extraction and enrichment.The test procedure was simple,fast,and high precision.The relative standard deviation was 4.85%~6.40%,and the recovery was 85.6%~108.8%.
