Manufacturing Quality Control of Bis(tetrabutylammonium) dichromate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (C16H36N2CrO7) | Redox Titration with Fe2+ | Quantifies Cr(VI) by titration with standardized ferrous ammonium sulfate under acidic conditions, using diphenylamine sulfonate indicator. |
| Moisture Content | Karl Fischer Titration | Determines water content via coulometric or volumetric reaction between water and iodine generated electrochemically in a methanol-based reagent. |
| Heavy Metal Impurities (Pb, Cd, Hg, As) | ICP-MS | Measures trace heavy metals by ionization in plasma and mass spectrometric detection with high sensitivity and multi-element capability. |
| Chloride Ion (Cl-) | Potentiometric Titration with AgNO3 | Quantifies chloride by titration with silver nitrate using a silver/silver chloride electrode to detect the endpoint potential shift. |
| Sulfate Ion (SO4^2-) | Gravimetric Analysis | Precipitates sulfate as BaSO4 under controlled conditions and determines purity from the dried precipitate mass. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities by ignition at 500-600 C and weighing the residual ash. |
| pH of Aqueous Solution | pH Potentiometry | Measures hydrogen ion activity in a 1% w/v aqueous suspension using calibrated glass electrode and reference electrode. |
| Organic Volatile Impurities | GC-FID | Separates and quantifies residual solvents and organic contaminants using capillary column gas chromatography with flame ionization detection. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution by analyzing angular variation in laser light scattering from dispersed particles in liquid medium. |
| Bulk Density | Tap Density Measurement | Measures mass per unit volume after standardized mechanical tapping of a known powder mass in a graduated cylinder. |
| Color | Visual Comparison or Colorimeter | Evaluates color intensity against standard platinum-cobalt scale or measures absorbance at specified wavelength in solution. |
| Solubility in Common Solvents | Qualitative Dissolution Test | Assesses complete dissolution behavior in specified solvents (e.g., acetone, methanol, water) under controlled temperature and agitation. |
