具有工业意义的金属铌及金属?的分析及制备的分离法是困难的,文内系统的整理了主要的分离法或聚集法,阐明了它们的基础,那些利用低的氧化级或中间的水解级不同安定性的操作法显得特殊重要和适宜。
It is difficult to analyze and prepare separations of metals with the industrial significance of niobium and metals. The main methods of separation or aggregation are summarized systematically in the text to elucidate their basis. Those that utilize low levels of oxidation or intermediate hydrolysis Different levels of stability of the method of operation is particularly important and appropriate.
