Manufacturing Quality Control of COPPER(I) SELENIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Copper Content | EDTA Titration | Complexometric titration using EDTA at pH 10 with murexide indicator; Cu2+ forms stable complex with EDTA. |
| Selenium Content | Gravimetric Analysis (as SeO2) | Precipitation of selenium as SeO2 after oxidation and volatilization, followed by weighing. |
| Impurity Metals (Fe, Pb, Ni, Zn) | ICP-OES | Multi-element quantification based on intensity of element-specific atomic emission lines in plasma. |
| Chloride Content | Argentometric Titration (Mohr method) | Titration with AgNO3 using K2CrO4 indicator; formation of red Ag2CrO4 signals endpoint after Cl- precipitation. |
| Sulfate Content | Barium Sulfate Gravimetry | Precipitation of SO4(2-) as BaSO4 in acidic medium, followed by filtration and weighing. |
| Loss on Ignition (LOI) | Thermogravimetric Analysis | Mass loss measured upon heating to 1000 C under air; reflects moisture, carbonates, and volatile impurities. |
| Particle Size Distribution | Laser Diffraction | Analysis of angular scattering pattern of laser beam passed through dispersed sample to calculate size distribution. |
| Bulk Density | ASTM D1895 Method A | Measurement of mass per unit volume for freely settled powder in standardized cylinder. |
| Water Soluble Matter | Gravimetric Analysis | Extraction with deionized water, filtration, evaporation, and residue weighing. |
| pH of Aqueous Slurry | Potentiometric Measurement | Electrode-based measurement of H+ activity in 10% w/w aqueous suspension. |
| Residue on Sieve (e.g., 45 um) | Dry Sieving | Mechanical separation using standard woven-wire test sieve; mass of oversize fraction determined. |
| Total Organic Carbon (TOC) | High-Temperature Catalytic Oxidation | Combustion at 680 C with Pt catalyst; CO2 produced is quantified by NDIR detection. |
