摘要

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.

Abstract

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.
