By means of /sup 51/Cr as a radiotracer, the behavior of Cr(III) and Cr(VI) in a graphite furnace was investigated. After the addition of a mixture of trifluoroacetylacetone, tetramethylammonium hydroxide, and 0.5 M sodium acetate (1:2:2) to a water or urine sample, Cr(III) can quantitatively be removed from a graphite tube combined with an L'vov platform or from a tungsten-impregnated graphite tube without an L'vov platform at 400/sup 0/C while Cr(VI) quantitatively remains in the furnace up to a temperature of 1200/sup 0/C.
