Abstract A simple and rapid wet-digestion procedure is described in which flour samples containing bound and unbound mercury are decomposed, using a sulfuric-nitric acid mixture in the presence of small amounts of vanadium pentoxide. Fortification studies with 3 organomercuric compounds on mixed cereal flour indicate average recoveries in excess of 96% in the 20–500 ppb range. This wet digestion method is compared with the Klein procedure to illustrate the advantages and significance of the vanadium pentoxide oxidation.

Abstract The wet ashing–dry ashing procedure for destruction of organic matter in high-fat foods for subsequent fluorimetric determination of selenium was investigated. Samples were decomposed by predigestion with nitric acid and dry-ashed with magnesium nitrate and hydrochloric acid. Selenium was recovered quantitatively through the total procedure. Detection limit was about 4 ppb. Accuracy was tested by analysis of several reference materials and by comparison with the wet-digestion method. The present method can be used conveniently for selenium determination in high-fat foods.
