Adding a new reagent (CDSR-1) to aqueous solution, a volatile cadmium compound could be generated by reacting with sodium tetrahydroborate at room temperature. The detection limit of nondispersive atomic fluorescence spectrometry with argon-hydrogen mini-flame and heated quartz atomizer was 0.08mg/ml (36', 0.8ml sample volume), and the RSD was 1.3% (5ng/ ml, Cd, n=12). This method has been proved to be reliable, sensitive and rapid, its relative sensitivity was comparable with that of the graphite furnace AAS...
