Manufacturing Quality Control of COBALT(II) SELENIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Cobalt Content | Titration with EDTA | Complexometric titration using EDTA at pH 5-6 with sulfosalicylic acid indicator; Co2+ forms stable complex with EDTA. |
| Selenium Content | Hydride Generation AAS (HG-AAS) | Reduction of Se to volatile hydride (H2Se) followed by atomization and absorption measurement at 196.0 nm. |
| Impurity Metals (Fe, Cu, Ni, Pb, Cd) | ICP-OES | Multi-element quantification by measuring characteristic atomic emission intensities after plasma atomization/excitation. |
| Loss on Ignition (LOI) | Gravimetric Method | Mass loss determined by heating sample at 1000 C for 1 h; reflects moisture, volatiles, and organic residues. |
| Water Soluble Matter | Gravimetric Filtration | Extraction with deionized water, filtration, evaporation, and weighing of non-volatile residue. |
| Particle Size Distribution | Laser Diffraction | Measurement of light scattering pattern from dispersed particles in liquid medium to calculate size distribution. |
| Specific Surface Area (BET) | Gas Adsorption (N2 BET) | Quantification of N2 gas adsorbed at liquid nitrogen temperature; surface area calculated using Brunauer-Emmett-Teller theory. |
| Bulk Density | Tapped Density Method | Mass per unit volume measured after standardized tapping of powder in calibrated cylinder. |
| pH of Aqueous Slurry | Potentiometric Measurement | pH electrode measurement of 10% w/w aqueous slurry; indicates surface acidity/basicity and hydrolysis tendency. |
| Residue on Sieve (45 um) | Dry Sieving | Mechanical separation using standard 45 um sieve; determines coarse particle fraction by mass. |
| Sulfate Content | Barium Chloride Turbidimetry | Precipitation of SO4(2-) as BaSO4; turbidity measured spectrophotometrically at 420 nm. |
| Carbon Residue | Combustion Analysis | High-temperature oxidation in oxygen stream; residual carbon measured as CO2 by IR detection or gravimetrically. |
