Abstract

By using the ammonium pyrrolidinedithiocarbamate (APDC) — methylisobutyl ketone (MIBK) extraction system Sb(III) is extracted into the organic phase. Sb(III) is directly determined in this organic phase by hydride generation AAS using NaBH4/dimethylformamide solution as reducing agent. Sb(V) is determined in the aqueous phase using the same technique.
