SEPARATION OF NIOBIUM AND TANTALUM BY N-BENZOYL-N-PHENYLHYDROXYLAMINE

Journal Article · · Analytica Chimica Acta (Netherlands)

The pH range 3.5 to 6.5 for the complete precipitation of niobium and a pH below 1.5 for the precipitation of tantalum in separation and gravimetric analysis using N-benzoyl-N-phenylhydroxylamine are examined. Theyare verified to be correct. There is no possibility of the precipitation of hydrous oxide, even when the niobium or the tantalum solution is made ammonical in these pH ranges. (N.W.R.)
