Manufacturing Quality Control of tetraammonium ethylenediaminetetraacetate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (EDTA Ammonium Content) | Acid-Base Titration with Standardized Cu²⁺ or Zn²⁺ Solution | Complexometric titration using metal ion standard solution at controlled pH; endpoint detected by metallochromic indicator. |
| pH (1% aqueous solution) | Potentiometric pH Measurement | Determination of hydrogen ion activity using calibrated pH electrode in aqueous solution. |
| Heavy Metals (as Pb) | ICP-OES or AAS | Quantification of trace heavy metals after acid digestion and matrix-matched calibration. |
| Chloride (Cl⁻) | Argentometric Titration (Mohr or Potentiometric) | Titration with standardized AgNO₃ solution; chloride forms insoluble AgCl precipitate. |
| Sulfate (SO₄²⁻) | Gravimetric Analysis or Ion Chromatography | Precipitation as BaSO₄ followed by weighing, or separation and quantification via anion-exchange chromatography. |
| Loss on Drying (LOD) | Thermogravimetric Analysis (TGA) or Oven Drying | Mass loss measured after heating at 105 °C to constant weight, reflecting volatile content and residual moisture. |
| Iron (Fe) | ICP-OES or Colorimetric UV-Vis (with 1,10-phenanthroline) | Oxidation to Fe²⁺ followed by complex formation and absorbance measurement at ~510 nm, or direct elemental analysis. |
| Appearance & Clarity | Visual Inspection in Solution | Assessment of physical state (white crystalline powder) and clarity of a defined aqueous solution against standard references. |
| Residue on Ignition | Gravimetric Ash Residue Analysis | Mass of non-volatile inorganic residue remaining after high-temperature (500–600 °C) ignition. |
| Water Content (Karl Fischer) | Coulometric or Volumetric Karl Fischer Titration | Electrochemical or volumetric determination of water via iodine–sulfur dioxide reaction in anhydrous methanol medium. |
