Abstract
A method is presented for the determination of fourteen elements in pure iron by means of destructive thermal neutron activation analysis. By means of an anion- and cation-exchange procedure in 1 M hydrofluoric acid, the iron matrix is separated from a large number of elements, which are further separated in groups. W, Mo, Ta, Sn, Sb and Sc are found and measured as one group on the anion-exchange resin. Cu and Co, and Zn and Ag, are two groups obtained from the cation exchange procedure. For the elements Ga, Ni, Cr and As which cannot be included in the general group separation scheme, special individual methods are described.
