随着钽、铌在电子、化工、原子能、钢铁、航空和宇宙航行等领域内的重要应用,钽、铌的分析化学作为分析化学的一个分支在二十多年的时间里得到了迅速的发展。虽然近年来仪器分析日益显示出快速、灵敏的优越性,但是出于对结果准确性和精密度的考虑,湿法化学分析仍然占着钽、铌分析中的主导地位,标样标准值的确定和标准方法的制订尤其是这样。本文试图对钽、铌中杂质元素的化学分析方法,以吸光光度法为主作一综合介绍。
With the important applications of tantalum and niobium in the fields of electronics, chemical engineering, atomic energy, steel, aviation and aerospace, the analytical chemistry of tantalum and niobium has been rapidly developed as a branch of analytical chemistry for more than two decades . Although instrumental analysis is increasingly showing rapid and sensitive superiority in recent years, wet chemical analysis still dominates the analysis of tantalum and niobium because of the accuracy and precision of the results. The determination of standard values of standard samples This is especially true of the standard methodologies. This article attempts to tantalum, niobium in the chemical analysis of impurity elements to absorbance spectrometry as a comprehensive introduction.
