Manufacturing Quality Control of potassium azide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (K N3 content) | Acid-base titration with HCl | Quantifies azide ion by reaction with standardized HCl and back-titration with NaOH using methyl orange indicator. |
| Moisture content | Karl Fischer titration | Measures water content via coulometric or volumetric reaction between water and iodine in pyridine/methanol medium. |
| pH of aqueous solution | Potentiometric pH measurement | Determines hydrogen ion activity in a 1% w/v aqueous solution using calibrated pH electrode. |
| Heavy metals (as Pb) | Atomic absorption spectroscopy (AAS) | Quantifies total heavy metals after wet digestion by measuring absorbance at characteristic wavelengths for lead. |
| Sulfate (SO4) | Gravimetric analysis | Precipitates sulfate as BaSO4 after acidification and barium chloride addition; mass of precipitate determines sulfate content. |
| Chloride (Cl) | Argentometric titration (Mohr method) | Titrates chloride with standardized AgNO3 using potassium chromate indicator to detect endpoint via red Ag2CrO4 formation. |
| Iron (Fe) | ICP-OES | Measures Fe emission intensity at specific wavelength after acid digestion and nebulization into plasma. |
| Sodium (Na) | Flame photometry | Quantifies sodium based on characteristic yellow emission intensity when atomized in air-acetylene flame. |
| Insoluble matter | Gravimetric filtration | Determines residue mass after dissolving sample in water, filtering through pre-weighed sintered glass crucible, and drying. |
| Nitrate (NO3) | UV-Vis spectrophotometry | Measures absorbance of nitrate after reduction to nitrite and diazotization-coupling to form colored azo dye. |
| Particle size distribution | Laser diffraction | Analyzes scattered laser light intensity pattern to calculate particle size distribution in aqueous suspension. |
| Organic impurities | GC-FID | Detects and quantifies volatile organic contaminants after solvent extraction using flame ionization detection. |
