Manufacturing Quality Control of Sodium 1-naphthalenesulfonate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (NaC10H7SO3 content) | Acid-Base Titration | Neutralization of sulfonate group with standardized HCl after acidification and back-titration with NaOH. |
| Moisture Content | Karl Fischer Titration | Quantitative reaction of water with iodine and sulfur dioxide in pyridine/methanol medium. |
| pH (1% aqueous solution) | pH Meter Measurement | Electrochemical measurement using calibrated glass electrode in diluted aqueous solution. |
| Water Insolubles | Gravimetric Analysis | Filtration through pre-weighed sintered glass crucible, drying, and weighing of residue. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Atomization of sample in flame or graphite furnace followed by absorption measurement at characteristic wavelength. |
| Sulfate (SO4) Impurity | Barium Sulfate Gravimetric Method | Precipitation as BaSO4 after removal of interfering ions, followed by ignition and weighing. |
| Chloride (Cl) Impurity | Potentiometric Titration with AgNO3 | Titration with silver nitrate using silver indicator electrode to detect endpoint via potential change. |
| Iron (Fe) Impurity | ICP-OES | Excitation of atomized sample in plasma; quantification via emission intensity at Fe-specific wavelength. |
| Color (APHA) | UV-Vis Spectrophotometry | Measurement of absorbance at 430 nm in aqueous solution against platinum-cobalt standard scale. |
| Residue on Ignition | Gravimetric Analysis | Ignition of sample at 500-600 C to remove organics, then weighing of inorganic ash residue. |
| Sodium (Na) Content | Flame Photometry | Atomization in flame and measurement of characteristic orange-yellow emission intensity. |
| Organic Impurities (related substances) | HPLC-UV | Separation on reversed-phase column with UV detection at 254 nm; identification and quantification vs reference standards. |
