Electroanalytical study of the catalytic enhancement by antimony(III) of the anodic wave for bromide in acidic media.
The results are given of a study using a rotating disk electrode to develop an amperometric method for the determination of Sb(III) in acidic media, based on the catalytic increase of the limiting anodic current for Br(-). Analytical application was successful provided the bulk concentration of antimony(III) was less than that of bromide. The enhancement technique was also applied to the determination of Sb(III) injected into a stream of electrolyte passing through a platinum coulometric detector.
