Industrial Applications of Chromium sulfate,basic,solid
| Industry | Application | Process |
|---|---|---|
| Leather Industry | Used as a tanning agent for preliminary leather tanning and stabilization of collagen structure | Basic chromium sulfate solution is impregnated or sprayed onto raw hides, with pH and temperature controlled to facilitate the tanning reaction |
| Dyes and Pigments Industry | Used as a chromium mordant to improve dye fixation and lightfastness on fibers | Present concurrently with dyes during dyeing, forming insoluble chromium complexes that deposit on fiber surfaces |
| Wood Preservation | Used as a preservative component to enhance wood resistance against fungi and insects | Formulated with chromates or copper salts and introduced into wood cell walls via pressure impregnation |
| Catalyst Manufacturing | Used as a precursor in the production of chromium-based catalysts | Thermally decomposed or calcined to form chromium oxide, applied in dehydrogenation, oxidation, and other catalytic reactions |
| Ceramics and Glass Industry | Used as a colorant to impart green or dark green hues | Mixed with other metal oxides and incorporated into glazes or glass melts prior to high-temperature sintering |
Manufacturing Quality Control of Chromium sulfate,basic,solid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Chromium Content | Redox Titration with Ammonium Ferrous Sulfate | Chromium(VI) is reduced to Cr(III) and titrated with standardized ferrous ammonium sulfate using diphenylamine sulfonate indicator. |
| Basicity (as % NaOH equivalent) | Acid-Base Titration | Sample is dissolved and titrated with standardized HCl using methyl orange indicator; basicity calculated from acid consumed. |
| Sulfate Content | Gravimetric Analysis | Sulfate is precipitated as BaSO4 after digestion and ignition; mass of precipitate used to calculate sulfate content. |
| Moisture Content | Karl Fischer Titration | Water reacts stoichiometrically with Karl Fischer reagent (iodine, sulfur dioxide, pyridine, methanol); endpoint detected electrometrically. |
| Insoluble Matter | Gravimetric Filtration | Sample is dissolved in water, filtered through pre-weighed sintered glass crucible, dried and weighed. |
| pH of 10% Aqueous Suspension | Potentiometric Measurement | pH electrode measures hydrogen ion activity in a standardized suspension prepared per ASTM D1193. |
| Heavy Metals (Pb, Cd, As, Hg) | ICP-OES | Elements are atomized and excited in argon plasma; characteristic emission intensities quantified against calibration standards. |
| Iron Impurity | UV-Vis Spectrophotometry | Iron forms colored complex with 1,10-phenanthroline at pH 3–9; absorbance measured at ~510 nm. |
| Chloride Content | Argentometric Titration | Chloride ions react with standardized silver nitrate solution using potassium chromate indicator (Mohr method). |
| Loss on Ignition | Thermogravimetric Analysis | Mass loss measured after heating sample at 800 C for 1 hour; reflects volatile impurities and decomposition products. |
| Bulk Density | ASTM D1895 Method A | Mass of material freely poured into calibrated cylinder; density calculated from mass/volume ratio. |
| Particle Size Distribution | Laser Diffraction | Scattering pattern of laser beam passing through dispersed particles is analyzed to determine size distribution profile. |
