Manufacturing Quality Control of CHROMOTROPIC ACID DISODIUM SALT DIHYDRATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration with Standardized HCl | Quantifies chromotropic acid disodium salt by back-titration after acid hydrolysis and neutralization. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Measures total heavy metal content via flame or graphite furnace AAS after acid digestion. |
| Chloride Impurity | Potentiometric Titration with AgNO₃ | Determines chloride ions by silver nitrate titration using a silver indicator electrode. |
| Sulfate Impurity | Gravimetric Analysis | Precipitates sulfate as BaSO₄ under controlled acidic conditions and determines mass after ignition. |
| Loss on Drying (LOD) | Thermogravimetric Analysis (TGA) or Oven Drying at 105 °C | Measures volatile content (e.g., water, solvents) by mass loss upon controlled heating. |
| Iron (Fe) Content | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Quantifies trace Fe after acid digestion using element-specific plasma emission intensity. |
| pH of Aqueous Solution (1% w/v) | Potentiometric pH Measurement | Determines hydrogen ion activity in aqueous solution using calibrated glass electrode. |
| UV-Vis Absorbance (λmax ~570 nm) | Ultraviolet-Visible Spectrophotometry | Verifies identity and assesses purity via characteristic absorbance peak in acidic medium post-diazotization. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities by mass of residue after high-temperature ashing (700–800 °C). |
