<I>Activation analysis was carried out on the purified iron and aluminum to study the behavior of trace impurities on purification process, and to estimate the purity of the purified samples.</I><BR><I>Thermal neutrons with high Cd ratio through</I> D<SUB>2</SUB>O <I>column or graphite column were used for the activation of samples to reduce the interference effects by fast neutrons, the reactions, (n, p) or (n, α), from matrix elements.</I><BR><I>On the zone refined aluminum, the segregation of impurity elements was cleary observed. In the case of iron, decrease of impurity content was confirmed on superposing the various purification processes.</I>
