A voltammetric method for quantitative determinations of azide and lead in lead azide is presented. The determination of azide is based on oxidation of azide ions at a carbon paste electrode and that of lead on reduction at a dropping-mercury electrode in a 0.1 M acetate solution at pH 4.6. This voltammetric method is also applied in determination of trace amounts of azide in evinronmental samples. The limit of detection is about 0.05 mg NaN3 per m3 of air, when 25 L of air is passed through 10 ml 0.2 M KOH for absorption of air.
