摘　　要：文章研究了采用电感耦合等离子体原子发射光谱法测定铌铁中铌含量的测定方法试样采用盐酸、氢氟酸、硝酸溶解,加入钼作为内标元素,显著提高了铌铁中铌测定的精密度和准确度通过试验表明,该方法操作简单、快速、准确,相对标准偏差为(n=10)0.14%,回收率在99%-101%之间,能满足日常检验和科研需要.This paper deals with the ICP-AES method of determinantion of Niobium content in Ferrocolumbium.The sample will be decomposed by hydrochloric acid,nitric acid and hydrofluoric acid,adding Molybdenum as internal standard element can improve the accuracy and precision of the detenninantion .The experiment show that this method is saniple.rapid,sensitive. The relative standard deviation is(n=10) 0.14%,the recovery is between 99%-101%.It can satisfy the demand of routine test and research.
