Manufacturing Quality Control of REACTIVE BLACK 5
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Quantifies dye concentration based on absorbance at characteristic lambda-max using Beer-Lambert law with reference standard. |
| Moisture Content | Karl Fischer Titration | Measures water content via stoichiometric reaction between water and iodine in a methanol-based reagent. |
| Inorganic Salt (Na2SO4) | Gravimetric Analysis | Precipitates sulfate as BaSO4, followed by drying and weighing to determine salt content. |
| Heavy Metals (Pb, Cd, Cr, As, Hg) | ICP-OES | Simultaneously quantifies trace metals after acid digestion by measuring element-specific atomic emission intensities. |
| pH of 1% Aqueous Solution | Potentiometric Titration | Determines hydrogen ion activity using calibrated pH electrode in standardized aqueous dispersion. |
| Water Solubility | Visual Inspection & Filtration | Evaluates complete dissolution in distilled water at specified temperature and concentration, confirmed by absence of residue after filtration. |
| Chloride Ion Content | Argentometric Titration (Mohr method) | Titrates Cl- with standardized AgNO3 solution using K2CrO4 indicator; endpoint signaled by red Ag2CrO4 precipitate. |
| Ash Content | Gravimetric Analysis (Ignition at 550 C) | Measures non-volatile residue after high-temperature incineration of sample in muffle furnace. |
| Substantivity (on Cotton) | Spectrophotometric Dye Uptake | Compares absorbance of dye bath before and after dyeing to calculate percentage fixation on cotton substrate. |
| Fastness to Light | Xenon Arc Fadeometer Testing | Exposes dyed fabric to controlled xenon lamp radiation and assesses color change against Blue Wool Scale. |
| Fastness to Washing | ISO 105-C06 Testing | Evaluates color change and staining after mechanical laundering under standardized time, temperature, and detergent conditions. |
| Particle Size Distribution | Laser Diffraction | Measures volume-weighted particle size distribution in aqueous dispersion using Mie scattering theory. |
