A method for the determination of hafnium in zirconium metal was studied. Hafnium was enriched from a hydrochloric acid solution of zirconium with four steps of thiocyanate-hexone extraction-stripping method. After the several steps of extraction, pure hafnium fraction was obtained by passing the solution through the cation exchanger resin column, and eluting with the mixture of 0.45M nitnic acid and 0.095M citric acid as an eluant. Combining the isotope dilution method and the above-mentioned method, hafnium, which existed from 0.025 to 0.1% in zirconium, was determined. (auth)
