“…The determination of hafnium in zirconium was included in a general description of neutron activation analysis (133). Separations by means of ion-exchange techniques were used along with neutron activation analysis for the determination of hafnium in scandium (37), titanium (463), silicates (222) and soils, minerals, and rocks (81). A separation by precipitation as hafnium phenyiarsonate was used in the determination of hafnium in natural samples (82).…”
