Manufacturing Quality Control of FAST BLACK K SALT PRACTICAL GRADE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Potassium Content | Flame Photometry | Measures potassium ion emission intensity at characteristic wavelength in flame. |
| Sulfur Content | Gravimetric Analysis | Precipitates sulfate as BaSO4 and determines mass after ignition. |
| Chloride Impurity | Argentometric Titration | Titration with silver nitrate using potentiometric or chromate endpoint detection. |
| Heavy Metals (Pb, Cd, Hg) | ICP-OES | Quantifies trace metals by measuring atomic emission intensities in plasma. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water via iodine-sulfur dioxide reaction. |
| pH of Aqueous Solution | Potentiometric Measurement | Determines hydrogen ion activity using calibrated pH electrode in 1% w/v solution. |
| Insoluble Matter | Gravimetric Filtration | Filters sample solution, dries residue, and weighs to determine insoluble fraction. |
| Iron Content | UV-Vis Spectrophotometry | Measures absorbance of Fe(II)-1,10-phenanthroline complex at ~510 nm. |
| Arsenic Content | Hydride Generation-AAS | Converts arsenic to arsine gas, then atomizes and quantifies by atomic absorption. |
| Loss on Drying | Thermogravimetry | Measures mass loss after heating at 105 C for 2 hours under controlled conditions. |
| Bulk Density | Tap Density Measurement | Determines mass per unit volume after standardized tapping of powder in graduated cylinder. |
| Particle Size Distribution | Laser Diffraction | Analyzes scattered laser light intensity to calculate size distribution based on Mie theory. |
