Manufacturing Quality Control of SODIUM AMMONIUM HYDROGEN PHOSPHATE TETRAHYDRATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Na2HPO4.NH4H2PO4 content) | Acid-base titration | Quantifies total phosphate and ammonium content via sequential titration with standardized NaOH and HCl solutions. |
| Loss on drying | Gravimetric analysis | Measures mass loss after heating at 105 C to determine volatile components including water and residual ammonia. |
| pH of aqueous solution | Potentiometric measurement | Determines hydrogen ion activity in a 1% w/v aqueous solution using calibrated pH electrode. |
| Chloride (Cl-) | Argentometric titration | Quantifies chloride ions by titration with silver nitrate using potassium chromate indicator. |
| Sulfate (SO42-) | Barium sulfate gravimetric method | Precipitates sulfate as BaSO4 and determines mass after ignition and weighing. |
| Heavy metals (as Pb) | Colorimetric sulfide precipitation | Compares intensity of brown-black color formed with H2S under acidic conditions against lead standard. |
| Iron (Fe) | 1,10-Phenanthroline UV-Vis spectrophotometry | Forms orange-red complex with Fe2+; absorbance measured at ~510 nm for quantification. |
| Ammonium (NH4+) | Formaldehyde titration | Releases H+ from ammonium-formaldehyde reaction, titrated with standardized NaOH. |
| Sodium (Na) | Flame photometry | Measures characteristic emission intensity of sodium atoms in flame at 589 nm. |
| Phosphate (as P2O5) | Quinolino-molybdate spectrophotometry | Forms yellow phosphomolybdate complex reduced to molybdenum blue; absorbance measured at 820 nm. |
| Insoluble matter | Gravimetric filtration | Determines residue retained on ashless filter paper after dissolution and hot filtration. |
| Arsenic (As) | Gutzeit arsenic test | Generates arsine gas from sample under acidic reduction; detected by coloration on mercuric bromide paper. |
