Abstract

A method is proposed for the separation and determination of traces of hafnium(≧1 p.p.m.) in scandium metal. The metals, as sulfate complexes, are separated by anion exchange in sulfuric acid medium. Analysis by thermal neutron activation is based on the formation of 179m-hafnium (T1/2 = 19 sec) and 46m-scandium (T1/2 = 19.5 sec). The complete separation and determination requires only 1 h.
