| Leather processing | Coloration of leather | Immersion dyeing or spray dyeing |
Manufacturing Quality Control of CHLORANTINE FAST RED 5B
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Quantifies C.I. Direct Red 81 concentration based on absorbance at its lambda-max in standardized aqueous solution, using a certified reference standard for calibration. |
| Moisture Content | Karl Fischer Titration | Determines water content by coulometric or volumetric titration with iodine generated electrochemically or added reagent, reacting stoichiometrically with water. |
| Inorganic Ash | Gravimetric Analysis (Ignition at 550 C) | Measures non-volatile residue after controlled high-temperature incineration of sample, followed by precise weighing of the ash. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Simultaneously quantifies trace heavy metals after acid digestion by measuring element-specific emission intensities from plasma-excited atoms/ions. |
| Chloride Ion Content | Potentiometric Titration with AgNO3 | Detects chloride via argentometric titration using silver nitrate and a silver/silver chloride electrode to identify endpoint potential shift. |
| pH of Aqueous Solution | pH Meter Measurement | Measures hydrogen ion activity in a defined aqueous suspension or solution using a calibrated glass electrode system. |
| Water Solubility | Gravimetric Filtration and Drying | Determines fraction dissolved after agitation, hot filtration, drying of residue, and mass comparison against initial sample weight. |
| Organic Impurities (Related Substances) | HPLC-UV | Separates and quantifies structurally related compounds using reversed-phase chromatography and UV detection at characteristic wavelengths. |
| Iron Content | AAS (Flame Atomic Absorption Spectroscopy) | Quantifies Fe after acid digestion by measuring absorption of light at 248.3 nm by ground-state Fe atoms in an air-acetylene flame. |
| Sulfate Content | Gravimetric Analysis (BaSO4 Precipitation) | Precipitates sulfate as barium sulfate under controlled conditions, followed by filtration, ignition, and weighing of the dried precipitate. |
| Bulk Density | Tap Density Measurement (ASTM D1895) | Determines mass per unit volume after standardized tapping of a known mass in a graduated cylinder to simulate industrial handling conditions. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution by analyzing angular variation in intensity of laser light scattered by dispersed particles in liquid or air. |
