DETERMINATION OF NIOBIUM AND TANTALUM WITH CINNAMYL HYDROXAMIC ACID AND N- CINNAMOYL-N-PHENYLHYDROXYLAMINE

Journal Article · · Analytica Chimica Acta (Netherlands)

The determination and separation (from other ions) of niobium and tantalum by means of cinnamylhydroxamic acid and N-cinnamoyl-N- phenylhydroxylamine are described. Cinnamylhydroxamic acid permits the separation of both elements above pH 5.0 (titanium. zirconium. and molybdenum interferel and the niobium complex can be weighed after drying at 110 . With N- cinnamoyl-Nphenylhydroxylamine, the optimum conditions are slightly different; titanium, zirconium, vanadate, molybdate, tungstate, iron, tin, and antimony contaminate these precipitates.
