Industrial Applications of Mordant Black 13
| Industry | Application | Process |
|---|---|---|
| Textile Dyeing & Printing | Dyeing of protein fibers such as wool and silk | Acid mordant dyeing: requires pretreatment with potassium dichromate or other chromium salts; dyeing conducted under weakly acidic conditions (pH 2–6) to form chromium complexes that bind to the fiber |
| Leather Industry | Leather dyeing | Used as an acid mordant dye for dyeing chrome-tanned leather; uniform coloration achieved by controlling pH and adding mordants |
| Paper Dyeing | Anti-counterfeiting coloring of specialty papers (e.g., banknote paper, security paper) | Direct dyeing in acidic papermaking systems or co-application with mordants to impart lightfast and washfast gray-black shades |
Manufacturing Quality Control of Mordant Black 13
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Acidic Medium Gray BS content) | UV-Vis Spectrophotometry | Measures absorbance at characteristic wavelength (e.g., ~520 nm) and quantifies concentration via calibration curve using Beer-Lambert law. |
| Moisture Content | Karl Fischer Titration | Determines water content by coulometric or volumetric titration with iodine generated in situ via reaction with water. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Uses calibrated glass electrode to measure hydrogen ion activity in a standardized aqueous suspension (e.g., 1% w/v). |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Digests sample in acid matrix and quantifies elemental concentrations by measuring intensity of element-specific atomic emission lines. |
| Sulfate Impurity | Gravimetric Analysis | Precipitates sulfate as BaSO4 under controlled conditions and determines mass after ignition and drying. |
| Chloride Impurity | Argentometric Titration (Mohr method) | Titrates chloride with standard silver nitrate solution using potassium chromate indicator; endpoint signaled by red Ag2CrO4 precipitate. |
| Iron Impurity | Colorimetric Method (1,10-Phenanthroline) | Forms orange-red complex with Fe2+; absorbance measured at ~510 nm for quantification. |
| Ash Content | Gravimetric Analysis (Ignition at 550 C) | Heats sample to constant weight at specified temperature; residue mass represents inorganic ash content. |
| Particle Size Distribution | Laser Diffraction | Measures angular scattering pattern of dispersed particles in liquid or air to calculate size distribution based on Mie theory. |
| Bulk Density | Tap Density Measurement | Determines mass per unit volume after standardized tapping of a known mass in a graduated cylinder. |
| Solubility in Water | Gravimetric Filtration | Measures undissolved residue after stirring standardized suspension, hot filtration, and drying. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separates and quantifies residual solvents or organics using capillary column and flame ionization detection. |
