摘要：

A method is described for the determination of total antimony, extractable into 4 mol dm-3 HCl, and Sb(III), which combines a slurry procedure with hydride generation atomic absorption spectrometry. The lack of a matrix effect allows the analytical results to be obtained with a simple aqueous working curve. The detection limit in solid samples is 13.3 and 8.35 ng g-1 for Sb(III) and total antimony, respectively. The proposed method for the determination of total antimony provides a better recovery than that obtained by digestion with a mixture of HNO3-H2SO4-HClO4 but worse than that obtained by digestion with HF.
