The determination of Ta by isotope dilution method in the presence of Nb was investigated using the radioactive isotope 185Ta. Ta was separated from Nb as Ta-tannin precipitate in the optimum conditions of pH 1.9∼2.5 and of Ta/Nb ratio upto 1/50. If Nb was 100 times or more of Ta in content, reprecipitation was needed. The reciprocals of the specific activities of Ta2O5 precipitates were linear to the weights of Ta added. The recommended method gave accurate results for determination of Ta in steel.
