A new method for nondispersive atomic fluorescence spectrometric determination of trace antimony by hydride generation in organic phase is proposed. Antimony is extracted into tributyl phosphate (TBP) or is extracted by ammonium pyrrolidinel-carbo- dithioate (APDC) into methyl iso-butyl ketone (MIBK). The antimoy hydride generation is carried out in an aliquot of extraction solution by sodium tetrahydroborate (Ⅲ) in N, N-dimethyl formamide solution and anhydrous acetic acid, then it is determined by nondispersive atomic fluorescence spectrometry. The proposed method gives improved sensitivity and eliminates interfences. The method has been applied to the determination of trace antimony in water samples with satisfactory
