本文采用HNO3溶解样品,建立了电感耦合等离子体发射光谱法(ICP-AES)测定Bi-2223高温超导材料中铋、锶、钙、铜、铅元素含量的检测方法.在仪器最佳操作条件下,测得Bi-2223高温超导材料中各元素的检出限均不大于0.004%,相对标准偏差(RSD)均不大于0.8%,加标回收率介于98.7%~100.9%之间.说明该方法测试结果准确且稳定,可用于Bi-2223高温超导材料中铋、锶、钙、铜、铅元素含量的测定.
Determination of bismuth,strontium,calcium,copper and lead in Bi-2223 high-temperature superconducting material by ICP-AES method
This method uses nitric acid to dissolve samples.Systematically explores the method of inductively coupled plasma emission spectrometry(ICP-AES)for the determination of bismuth,strontium,calcium,copper,and lead in Bi-2223 high-temperature superconducting materials.Under the optimal conditions of the instrument,the detection limit of each element in Bi-2223 high-temperature superconducting material was measured not more than 0.004%,the relative standard deviation(RSD)was not more than 0.8%,and the recovery rate was between 98.7%and 100.9%.It shows that the test results of this method are accurate and stable,which is convenient for practical production and application,and used for the determination of bismuth,strontium,calcium,copper and lead in Bi-2223 high temperature superconducting material.
