· Talanta (England)
A method is described for the determination of tantalum and niobium in beryllium or beryllium oxide. These two elements are precipitated with cupferron, using zirconium as a collector. A further separation from other elements is obtained by passing a mixed chloride-fluoride solution through a column containing a strongly basic anion-exchange resin. Niobium and tantalum are selectively eluted from the column and finally determined spectrophotometrically. niobium with hydroquinone and tantalum with pyrogallol. For niobium, the method is accurate to plus or minus 5% or lO mu g, whichever is greater, and for tantalum it is accurate to plus or minus 10% or 3O mu g, whichever is greater. No interference was caused by the presence of 10-mg amounts of 68 elements. (auth)
