摘要
研究用2-(5-溴-吡啶偶氮)-5-二乙氨苯基酚(5-Br-PADAP)测定钢中铌的显色条件,所拟方法简捷实用,可测钢中0.010％～6.00％的铌。
Optimum conditions for the colour reaction of Nb ( V ) with 5-Br-PADAP are studied thoroughly and a method for the determination of Nb in steel is proposed. The method is proved to be simple rapid and easy to manipulate. It has been applied to the determination of 0. 010% to 6. 00% of Nb in steel with satisfactory results.
