| Industry | Application | Process |
|---|---|---|
| Textile Industry | Used for dyeing and printing cotton, linen, viscose rayon, and their blends | Direct dyeing, typically conducted under neutral or mildly alkaline conditions |
| Paper Industry | Used as a paper colorant | Added directly to the pulp or applied via surface sizing |
| Leather Industry | Used for leather dyeing | Immersion dyeing in acidic or neutral baths |
| Ink Manufacturing | Used as a red colorant in aqueous inks | Formulated as a water-soluble dye solution and incorporated into the ink system |
| Biological Staining | Used for staining cells or tissue sections in histology (less common) | Applied via immersion or drop staining using a prepared staining solution |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Measures absorbance at lambda-max (approx. 520 nm) and calculates concentration using Beer-Lambert law with certified reference standard. |
| Moisture Content | Karl Fischer Titration | Quantifies water via coulometric or volumetric titration using iodine-based reagent reacting stoichiometrically with water. |
| Ash Content | Gravimetric Analysis (Ignition at 550 C) | Determines inorganic residue after high-temperature incineration; mass loss on ignition reflects organic content. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Measures absorbance of ground-state atoms in flame or graphite furnace after acid digestion and matrix modification. |
| Water Soluble Matter | Gravimetric Analysis | Extracts sample with hot distilled water, filters, evaporates filtrate to dryness, and weighs residue. |
| Organic Impurities (Related Substances) | HPLC-UV | Separates components on reversed-phase column and detects impurities by UV absorption relative to main peak area. |
| pH of 1% Aqueous Suspension | pH Meter Measurement | Measures hydrogen ion activity in aqueous suspension using calibrated glass electrode pH meter. |
| Particle Size Distribution | Laser Diffraction | Analyzes angular scattering pattern of laser beam passing through dispersed particles to calculate size distribution. |
| Bulk Density | ASTM D1895 Method A (Tapped Density) | Determines mass per unit volume after controlled tapping of a graduated cylinder containing the powder. |
| Residue on Sieve (63 um) | Sieve Analysis | Quantifies oversize particles retained on standard 63 um mesh sieve after mechanical agitation under specified conditions. |
| Chloride Content | Potentiometric Titration with AgNO3 | Measures chloride ions via silver nitrate titration using silver indicator electrode and endpoint detection at potential inflection. |
| Sulfate Content | Gravimetric Analysis (as BaSO4) | Precipitates sulfate as barium sulfate after acidification and digestion, then weighs dried precipitate. |
