Abstract
The determination of tin in the presence of a variety of metal ions ha s been studied by hydride generation atomic absorption spectrometry. T he results show serious depressing interference from transition metals . Such interference can be completely eliminated using potassium cyani de. A mechanism is put forward to interpret the effect of cyanide via the formation of a stable cyano-metal complex with the interfering met al before the harmful depressing effect of the latter takes place in t he quartz cell.
