Industrial Applications of Sodium diphenylamine-4-sulfonate
| Industry | Application | Process |
|---|---|---|
| Chemical Analysis | Redox Indicator | Used to indicate the endpoint in redox titrations—such as potassium dichromate (or other strong oxidant) titrations for iron determination—where the oxidized form is reddish-purple and the reduced form is colorless, with a transition potential of approximately +0.85 V. |
| Chemical Analysis | Vanadium Determination | Employed as a colorimetric reagent or redox indicator in vanadium analysis, participating in redox reactions to quantify vanadium content. |
| Electrochemical Industry | Battery Additive | Added to battery electrode materials to enhance electrical conductivity or serve as a redox mediator to improve battery performance. |
| Industrial Water Treatment | Redox Control | Applied in industrial recirculating water or wastewater treatment systems to monitor or indicate the oxidation-reduction potential (ORP) status of the water. |
Manufacturing Quality Control of Sodium diphenylamine-4-sulfonate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies active component by titration with standardized HCl using methyl orange indicator. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric reaction between water and Karl Fischer reagent. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determines hydrogen ion activity using calibrated pH electrode in 1% w/v aqueous solution. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after acid digestion by measuring absorbance at characteristic wavelengths. |
| Sulfate Impurity | Gravimetric Analysis | Precipitates sulfate as BaSO4 under controlled conditions and determines mass after drying. |
| Chloride Impurity | Argentometric Titration | Titrates chloride with standardized AgNO3 using potassium chromate indicator. |
| Iron (Fe) Content | ICP-OES | Measures Fe concentration after sample digestion by detecting atomic emission at specific wavelength. |
| Loss on Drying | Gravimetric Method | Determines volatile matter by weight loss after drying at 105 C for 2 hours. |
| Organic Impurities | HPLC-UV | Separates and quantifies related substances using reversed-phase column and UV detection at 254 nm. |
| Residue on Ignition | Gravimetric Method | Measures non-volatile inorganic residue after ignition at 600 C for 30 minutes. |
| Solubility in Water | Visual Observation | Evaluates complete dissolution of specified amount in distilled water at 20 C with gentle agitation. |
| Appearance | Visual Inspection | Assesses physical state, color, and absence of visible foreign particles against white background. |
