摘要
研究了新试剂三溴偶氮溴膦 (4 BPA TB)与稀土元素的显色反应。 0 .96mol·L- 1HNO3介质中 ,稀土元素与 4 BPA TB的显色反应灵敏度一致。利用此反应性质 。
In a 0.96mol·L -1 HNO 3 solution tribromo bromophosphonazo (abbreviated as 4 BPA TB) reacts with trivalent cations of rare earth elements to form colored complexes having nearly same sensitivity. Hence, this new color reagent was used satisfactorily in the determination of total rare earth contents in some steel samples.
