| Industry | Application | Process |
|---|---|---|
| Chemical Industry | Oxidizing agent | Used as a raw material or intermediate in the production of other chromium compounds, such as chrome yellow pigments and dyes |
| Dye Industry | Manufacture of chrome yellow pigment | Used as a raw material in the synthesis of chrome yellow pigment |
| Environmental Protection Industry | Wastewater treatment | Applied as an oxidizing agent under specific conditions to treat certain types of industrial wastewater |
| Leather Industry | Leather tanning | Applied in chrome tanning processes to enhance leather quality and durability |
| Agriculture | Fertilizer manufacturing | Used as a raw material for producing chromium-containing micronutrient fertilizers; environmental impact and safety considerations must be addressed |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Calcium Content | EDTA Complexometric Titration | Calcium ions form a stable complex with EDTA at pH 10; endpoint detected using Eriochrome Black T indicator. |
| Chromium(VI) Content | Redox Titration with Ferrous Ammonium Sulfate | Cr2O7(2-) oxidizes Fe2+ to Fe3+ in acidic medium; endpoint detected by diphenylamine sulfonate indicator. |
| Water Insolubles | Gravimetric Analysis | Sample dissolved in water, filtered through pre-weighed sintered glass crucible, dried and weighed. |
| Moisture Content | Karl Fischer Coulometric Titration | Electrochemical generation of iodine reacts stoichiometrically with water; current measurement correlates to water mass. |
| pH of Aqueous Solution | Potentiometric Measurement | pH electrode measures hydrogen ion activity in a 1% (w/v) aqueous solution at 25 C. |
| Heavy Metals (Pb, Cd, Ni, etc.) | ICP-OES | Elements atomized and excited in argon plasma; characteristic emission intensities quantified against calibration standards. |
| Sulfate Impurity | Barium Chloride Turbidimetry | SO4(2-) reacts with Ba2+ to form BaSO4 precipitate; turbidity measured spectrophotometrically at 420 nm. |
| Chloride Impurity | Potentiometric Titration with Silver Nitrate | Cl- reacts with Ag+ to form AgCl precipitate; endpoint detected by silver ion-selective electrode. |
| Iron Impurity | UV-Vis Spectrophotometry (1,10-Phenanthroline) | Fe2+ forms orange-red complex with 1,10-phenanthroline; absorbance measured at 510 nm. |
| Loss on Ignition | Thermogravimetric Analysis | Mass loss measured after heating sample at 800 C for 30 min; reflects decomposition of hydrates and organic residues. |
| Bulk Density | ASTM D1895 Method A | Mass of material freely poured into calibrated cylinder; density calculated from mass and volume. |
| Particle Size Distribution | Laser Diffraction | Scattering pattern of laser beam passing through dispersed particles is analyzed to calculate size distribution. |
