Manufacturing Quality Control of COBALT(II) BROMIDE HYDRATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Cobalt Content | Complexometric Titration with EDTA | Cobalt ions form a stable complex with EDTA at controlled pH; endpoint detected using an indicator such as sulfosalicylic acid. |
| Bromide Content | Potentiometric Titration with Silver Nitrate | Silver ions react stoichiometrically with bromide to form AgBr precipitate; endpoint determined by potential change using silver electrode. |
| Moisture Content | Karl Fischer Titration | Iodine reacts quantitatively with water in the presence of SO2, pyridine, and methanol; coulometric or volumetric detection of consumed iodine. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Elements are atomized and excited in argon plasma; characteristic emission intensities measured for quantitative multi-element analysis. |
| Iron Impurity | UV-Vis Spectrophotometry after Complexation | Fe3+ forms colored complex with 1,10-phenanthroline; absorbance measured at ~510 nm for quantification. |
| Chloride Impurity | Ion Chromatography | Chloride ions separated on anion-exchange column and detected by conductivity detector after elution with carbonate/bicarbonate buffer. |
| Sulfate Impurity | Gravimetric Analysis | Sulfate precipitated as BaSO4 under controlled conditions; dried and weighed to determine sulfate content. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Hydrogen ion activity measured using calibrated glass electrode and reference electrode in aqueous suspension or solution. |
| Loss on Drying | Thermogravimetric Analysis (TGA) | Mass loss measured upon heating sample to 105 C under nitrogen or air; reflects volatile content and residual solvents. |
| Particle Size Distribution | Laser Diffraction | Scattered laser light intensity pattern analyzed to calculate particle size distribution based on Mie theory. |
| Organic Impurities | GC-MS | Volatile organic impurities extracted and separated by gas chromatography, then identified and quantified via mass spectrometric detection. |
| Assay Purity (CoBr2) | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Quantitative determination of Co and Br isotopes with high sensitivity and accuracy; used for primary assay verification. |
