电感耦合等离子体发射光谱法测定纯银中锑元素的研究

摘要

The Antimony element in Sterling silver was determined by inductively coupled plasma-atomic emission spectrometry (ICP-AES) using hydrochloric acid precipitation.The two lines of 206.833nm and 217.581nm were surveyed by Thermo IRIS Intrepid Ⅱ ICP spectrometer,and discussed the interference problem of two lines.The relative standard deviations and spiked recoveries were 1.90％-2.28％ and 87.7％-92.6％,respectively.%使用盐酸沉淀分离银基体,电感耦合等离子体发射光谱法(ICP-AES)测定纯银中的锑元素,分析了美国热电Thermo IRIS Intrepid Ⅱ型ICP光谱仪推荐的206.833nm和217.581nm两条谱线,讨论两条谱线的干扰问题.方法的相对标准偏差和加标回收率分别为1.90％-2.28％和87.7％-93.0％.
