Abstract: | A rapid procedure has been developed for the mutual separation of antimony and arsenic using tribenzylamine as the extracting
agent. The extraction behaviours of Sb(III), Sb(V), As(III), As(V) and Au(III) have been studied as a function of the acidity
of the aqueous phase. Various factors which affect the extraction of these complexes have been studied and optimized. The
procedure was then applied to lead base alloy for the simultaneous determination of antimony, arsenic and copper. Chemical
recoveries were quantitative and only about one hour is required for the chemical processing of duplicate samples. |
