Manufacturing Quality Control of Phosphonic acid, disodium salt
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Sodium Content | Flame Atomic Absorption Spectroscopy (FAAS) | Quantifies Na+ ions by measuring absorption of characteristic wavelength light after atomization in a flame. |
| Phosphorus Content | UV-Vis Spectrophotometry (after ammonium molybdate reduction) | Measures phosphomolybdenum blue complex absorbance at ~820 nm following acidic oxidation and reduction. |
| Total Phosphorous Acid (H3PO3) Equivalent | Acid-Base Titration with NaOH | Determines titratable acidity corresponding to H3PO3 using phenolphthalein endpoint in aqueous solution. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Measures Cl- concentration via silver nitrate titration using silver indicator electrode and reference electrode. |
| Sulfate Impurity | Gravimetric Analysis | Precipitates SO4(2-) as BaSO4 under controlled conditions and determines mass after ignition. |
| Heavy Metals (Pb, Cd, As, Hg) | ICP-OES | Simultaneously quantifies trace metal elements by measuring atomic emission intensities after plasma atomization/excitation. |
| Water Content | Karl Fischer Coulometric Titration | Electrochemically determines water content based on stoichiometric iodine generation and reaction with water. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measures hydrogen ion activity using calibrated glass electrode in 1% w/v aqueous solution. |
| Insoluble Matter | Gravimetric Filtration | Determines residue mass after dissolving sample in water, filtering through pre-weighed sintered glass crucible, and drying. |
| Iron Impurity | Colorimetric Spectrophotometry (1,10-phenanthroline) | Forms orange-red Fe(II)-phenanthroline complex measured at ~510 nm after reduction and chelation. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying | Measures mass loss after heating at 105 C for 2 hours, indicating volatile content including moisture and residual solvents. |
| Assay (Na2HPO3 Purity) | Redox Titration with Iodine | Quantifies reducing capacity of HPO3(2-) by direct iodometric titration to stoichiometric endpoint. |
