Studies on the analytical chemistry of hafnium and zirconium. Part I. A review of methods for the determination of hafnium and zirconium in admixture

The available chemical and physical methods are discussed. The former are restricted to the determination of more than 0·1 per cent. of hafnium in zirconium. Emission spectrography, X-ray fluorescence and, especially, neutron-activation analysis can be used for trace hafnium determination in zirconium.
