Abstract
The effect of interferences of magnesium, strontium and ammonium on th e determination of lead by flame atomic spectrophotometry has been inv estigated. Ascrobic acid, citric acid and EDTA were used successfully for leveling the interfering effects caused by magnesium, stronium and ammonium at varying concentrations.
