I. Louw, ION-CHROMATOGRAPHIC DETERMINATION OF TRANSITION-METALS IN IRRADIATED NUCLEAR-REACTOR SURVEILLANCE SAMPLES, Fresenius' journal of analytical chemistry, 354(4), 1996, pp. 432-435
The determination of transition metal ions in radioactive (+/- 25 mu C
i/g) low-alloy steels (nuclear reactor surveillance samples) by ion ch
romatography (IC) is described. The analysis has been done directly wi
thout prior separation of the iron matrix. The eluted metal ions have
been detected with a UV-visible spectrophotometric detector after post
-column complexation with 4-(2-pyridylazo)resorcinol. The results are
in a good agreement with the certified values for the standard referen
ce material used. The method was applied to nuclear reactor surveillan
ce samples for the determination of Cu, Mn, Co and Ni.
