摘　　要：建立电感耦合等离子发射光谱仪测定三氯化钌溶液中杂质元素含量的方法.通过加入氧化剂将钌基体转化为四氧化钌挥发以消除基体干扰,优化了氧化剂、酸度、测定谱线等试验条件,结果表明,各杂质元素测定结果相对标准偏差(RSD,n=7)均小于5.00%,方法加标回收率为90.0%~106.0%.方法准确度高,重复性好,能满足实际生产需求.A method for the determination of impurity elements in ruthenium trichloride solution by the inductively coupled plasma atomic emission spectrometry has been established.The ruthenium matrix was converted into ruthenium tetrachloride by adding an oxidant to volatilize the sample to eliminate the matrix interference.The experimental conditions such as oxidant,acidity and determination spectrum were optimized.The results showed that the relative standard deviations(RSD,n=7)of the determination results of each impurity element were less than 5.00%,and the spiked recovery of the method was 90.0%~106.0%.The method is of high accuracy and good repeatability,which can meet the actual production needs.
