✦ Synopsis

Antimony (< 20 pg) can be determined spectrophotometrically at 640 nm after its adsorptive extraction as Brillant Green hexachloroantimonate(V) with microcrystalline l+dichlorobenxene after dissolution of the solid phase in toluene. The effects of reagent concentration, order and timing of addition, diverse ions and masking studies are reported. The system has been applied to the determination of antimony in steels.
