萃取光度法测定铌中微量钛

Methods For The Determination of Trace Titanium in Niobium by Extraction-Spectrometry

研究了Ｔｉ（Ⅳ）与二安替吡啶甲烷和ＳｎＣｌ２的显色反应。利用Ｔｉ（Ⅳ）－ＤＡＭ－ＳｎＣｌ２三元配合物在氯仿中的可溶性，建立了测定金属铌中微量钛的萃取光度法，测定下限达０．０００２％，变异系数为７％．

Abstract: The extraction-spectrometry method is presented for determing trace titanium in niobium. The results show that the inferior limit of detemination is 0.0002% and the variable coefficient is 7 %.
