Manufacturing Quality Control of Iron Oxide Black
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Iron Content | Redox Titration with KMnO4 | Oxidation of Fe2+ to Fe3+ by potassium permanganate in acidic medium; endpoint detected by persistent pink color. |
| Total Iron (Fe2+ + Fe3+) | ICP-OES | Quantification of total iron via atomic emission spectroscopy after acid digestion and nebulization. |
| Loss on Ignition (LOI) | Gravimetric Analysis | Mass loss measured after heating sample at 1000 C for 1 hour, indicating volatile impurities and moisture. |
| pH of Aqueous Slurry | Potentiometric Measurement | pH determined using calibrated glass electrode in a standardized water suspension (10% w/w). |
| Specific Surface Area (SSA) | BET Nitrogen Adsorption | Surface area calculated from nitrogen gas adsorption isotherm using Brunauer-Emmett-Teller theory. |
| Particle Size Distribution | Laser Diffraction | Size distribution derived from angular scattering pattern of laser beam passing through dispersed particles. |
| Water Soluble Salts | Conductivity Measurement | Electrical conductivity of aqueous extract correlates with concentration of soluble electrolytes (e.g., Na+, Cl-, SO42-). |
| Heavy Metals (Pb, Cd, Cr, Hg) | ICP-MS | Ultra-trace quantification of heavy metals after microwave-assisted acid digestion and mass spectrometric detection. |
| Chloride Content | Potentiometric Titration with AgNO3 | Titration with silver nitrate using silver indicator electrode; endpoint corresponds to AgCl precipitation completion. |
| Sulfate Content | Gravimetric Analysis as BaSO4 | Precipitation of sulfate as barium sulfate followed by filtration, drying, and weighing of precipitate. |
| Oil Absorption | ASTM D281 | Volume of linseed oil absorbed per 100 g sample until paste consistency is reached, indicating surface porosity and dispersibility. |
| Color Strength (Blackness) | Reflectance Spectrophotometry | Measurement of reflectance at 600 nm relative to standard black reference; lower reflectance indicates higher blackness. |
