Manufacturing Quality Control of FLUORESCENT WHITENING AGENT KCB
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison with certified reference standard using reversed-phase chromatography and UV detection at 345 nm. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content via reaction of iodine with sulfur dioxide in pyridine/methanol medium. |
| Ash Content | Gravimetric Analysis | Residue mass after incineration at 550 C determined by weight difference before and after high-temperature ashing. |
| pH of 1% Aqueous Solution | pH Meter Measurement | Potentiometric measurement of hydrogen ion activity in a standardized aqueous dispersion using calibrated glass electrode. |
| Heavy Metals (as Pb) | AAS | Atomic absorption spectroscopy quantifies lead concentration after acid digestion and matrix-matched calibration. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using silver indicator electrode; endpoint detected by potential inflection. |
| Solubility in Water | Visual Inspection and Filtration | Qualitative assessment of complete dissolution in distilled water at 25 C followed by filtration to confirm absence of residue. |
| Organic Impurities (Related Substances) | HPLC-DAD | Separation and detection of structurally related compounds using diode-array detection for spectral confirmation and quantitation. |
| Iron Content | ICP-OES | Multi-element plasma emission spectroscopy following microwave-assisted acid digestion and internal standard correction. |
| Bulk Density | Graduated Cylinder Method | Mass per unit volume measured by gently pouring sample into calibrated cylinder and tapping to settle without compaction. |
| Particle Size Distribution | Laser Diffraction | Analysis of light scattering pattern from dispersed particles to calculate volumetric size distribution. |
| Color Value (Yellowness Index) | Reflectance Spectrophotometry | Measurement of reflected light at specified wavelengths to compute yellowness index relative to white standard. |
