摘要：

High selectivity in measuring antimony by atomic absorption spectrometry is obtained by electrothermal atomisation of stibine in a stream of argon purging gas. This procedure requires a fast and reproducible reduction to stibine of the total antimony present in an aequeous solution. Optimum conditions for this reduction are reached by first transforming all antimony in the solution to an EDTA-chelate of antimony(III) which then reacts uniformly with sodium boron hydride to give stibine. Close temperature control is essential in decomposition of biological samples. © 1979 Springer-Verlag.
