Manufacturing Quality Control of Disodium 1,5-naphthalenedisulfonate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies active ingredient by titration with standardized NaOH solution using phenolphthalein indicator. |
| Sodium Content | Flame Photometry | Measures sodium ion emission intensity at characteristic wavelength in flame excitation. |
| Sulfate Impurity | Gravimetric Analysis | Precipitates sulfate as BaSO4 and determines mass after filtration and drying. |
| Heavy Metals (Pb, Cd, As, Hg) | ICP-OES | Simultaneously quantifies trace metals by measuring atomic emission intensities in inductively coupled plasma. |
| Water Content | Karl Fischer Titration | Determines water via stoichiometric reaction between water and iodine in pyridine/methanol medium. |
| pH of Aqueous Solution | Potentiometric Measurement | Measures hydrogen ion activity using calibrated pH electrode in 1% w/v aqueous solution. |
| Color (APHA) | UV-Vis Spectrophotometry | Compares absorbance at 430 nm against platinum-cobalt standard scale in diluted solution. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic residue after high-temperature ashing at 600-700 C. |
| Chloride Impurity | Argentometric Titration | Quantifies chloride by titration with standardized AgNO3 solution using potassium chromate indicator. |
| Organic Impurities | HPLC-UV | Separates and quantifies related organic compounds using reversed-phase column and UV detection at 254 nm. |
