Manufacturing Quality Control of Dibasic Lead Stearate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Lead Content | ICP-OES | Quantifies total lead by measuring atomic emission intensity of Pb at characteristic wavelengths after acid digestion. |
| Stearic Acid Content | Acid-Base Titration | Determines stearic acid equivalent by back-titration of excess standardized NaOH after saponification. |
| Basicity (as PbO) | Acid-Base Titration | Measures the alkaline oxide content via titration with standardized HCl using methyl orange indicator. |
| Moisture Content | Karl Fischer Titration | Determines water content by coulometric or volumetric reaction between water and iodine in pyridine/methanol medium. |
| Loss on Drying | Gravimetric Analysis | Measures volatile matter loss by weight difference before and after drying at specified temperature and time. |
| Heavy Metals (As, Cd, Hg) | ICP-MS | Simultaneously quantifies trace heavy metals after microwave-assisted digestion using isotopic mass spectrometry. |
| Chloride Content | Potentiometric Titration | Detects chloride ions by titration with AgNO3 using silver indicator electrode and reference electrode. |
| Iron Impurity | AAS | Measures Fe concentration by atomic absorption at 248.3 nm after sample dissolution and matrix matching. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution based on angular dependence of laser light scattering from dispersed particles. |
| pH of Aqueous Suspension | Potentiometric Measurement | Determines surface acidity/basicity by measuring H+ activity in a standardized water suspension using calibrated pH electrode. |
| Bulk Density | Gravimetric Volumetric Method | Calculates mass per unit volume by pouring sample into calibrated cylinder and measuring settled volume and weight. |
| Organic Volatiles (e.g., solvents) | GC-FID | Separates and quantifies residual organic solvents using capillary column gas chromatography with flame ionization detection. |
