Experiments for the determination of niobium in the presence of tantalum. After extraction from hydrochloric acid solutions with methyl isobutyl ketone. were run with solutions containing 10 mu g Nb and either 10. 200. 500. or 1000 mu g Ta. Results were in perfect agreement with those obtained with the same concentration of Nb in the absence of Ta. No interference was observed in any region of the spectrum of the colored solution that the extracted Nb formed with an alcohol solution of phenylfluorone. (M.C.G.)
