✦ Synopsis

Antimony(lI1) and -(V) were determined by flow-injection-hydride generation atomic absorption spectrometry (AAS) and by continuous-ffow-hydride

generation AAS and the analytical performances of the methods were compared. The optimum physical and chemical conditions for hydride generation and transport are given for the two methods. Both methods are more sensitive than the batch system. Total antimony was determined in sea water, but antimony(III) was below the detection limit (7 pg) of the proposed method.
