Niobium is separated from Ta and V by elution with 0.5 M HF in a column of chelating resin containing N-benzoyl-N-phenyl-hydroxylamine (NBPHA) as a function group. Niobium and tantalum can also be separated using their differential distribution coefficient and elution behavior, monitored by radiometric and also be spectrophotometric methods. 15 refs., 1 fig., 2 tabs.
