A fluorimetric analysis for the determination of nano gram amounts of selenium in rocks has been developed. The analysis has been made up by the procedures of decomposition of rocks, extraction, back-extraction of selenium, and its fluorimetric determination with 2,3-diaminonaphthalene (DAN). The reagent purification steps to minimize its blank value to low as possible have been discussed. Furthermore, the addition of EDTA-NaF to mask coexisting iron in the extraction has been discussed. This fluorimetric method has been applied to the rock reference materials issued by the Geological Survey of Japan.
