摘要 本文设计了一种电感耦合等离子发射光谱法对氧化铝载铱中铱的含量进行测定与分析。本文先确定了钠基体、铝基体的干扰消除方法,明确了分线谱线和标准曲线的制作,并且为验证文本方法的准确度进行了实验,结果表明应用该方法相对标准偏差小于3%,加标回收率为99.74%~102.08%。方法快速准确,与《贵金属化学分析方法铂、钯合金中铱量的测定硫酸亚铁电流滴定法》结果相吻合[1]。 In this paper,an inductively coupled plasma atomic emission spectrometry was designed to determine and analyze the content of iridium in alumina supported iridium.In this paper,the interference elimination methods of sodium matrix and aluminum matrix are determined,and the preparation of spectral lines and standard curves are defined.Experiments are carried out to verify the accuracy of the text method.The results show that the relative standard deviation of this method is less than 3%,and the recovery of standard addition is 99.74%~102.08%.The method is fast and accurate,which is consistent with the results of chemical analysis methods of precious metals-Determination of iridium content in platinum and palladium alloys-ferrous sulfate electrotitration[1].
