Notes:
Three methods are proposed for the assay of traces of hafnium in aluminium metal by neutron activation analysis. In the first method, the isotope 179mHf (T = 19 s), produced is counted after anionic resin exchange-separation in sulfuric acid medium. The two other methods, which are non-destructive, are based on the formation of 180mHf (T = 5,5 h) and 179mHf (T = 19 s). The latter method comprises an instrumental separation.
