Abstract
The urania-gadolinia fuels were dissolved with nitric acid. The analytical conditions of ICP-AES for the direct determinations of gadolinium in the uranium matrices without separation process were investigated. Based on the effect of uranium on gadolinium intensity, the best wavelength for gadolinium was 336.223 nm. The relative deviation of two methods, direct and indirect measurements with anion exchange chromatography, was less than 5 %. Therefore it was possible for this procedure directly to measure 5~10 wt.% of gadolinium in urania-gadolinia fuels without separation by ICP-AES.
