Manufacturing Quality Control of Poly(sodium 4-styrenesulfonate)
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Sodium Content | ICP-OES | Quantifies sodium ions by measuring atomic emission intensity at characteristic wavelengths after plasma atomization. |
| Sulfonate Group Content | Acid-Base Titration | Determines sulfonate groups via back-titration of excess standardized HCl after cation exchange. |
| Molecular Weight Distribution | GPC/SEC | Measures relative molecular weight distribution using size-based separation through porous columns with refractive index detection. |
| Residual Monomer (Styrene) | GC-FID | Quantifies unreacted styrene by gas chromatographic separation and flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines water via stoichiometric reaction between iodine, sulfur dioxide, and water in pyridine/methanol medium. |
| pH (1% aqueous solution) | Potentiometric Measurement | Measures hydrogen ion activity using calibrated pH electrode in standardized dilute aqueous solution. |
| Ash Content | Gravimetric Analysis | Determines inorganic residue mass after high-temperature combustion and cooling to constant weight. |
| Viscosity (Solution) | Capillary Viscometry | Measures flow time of polymer solution through calibrated capillary tube to calculate intrinsic viscosity. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Detects trace heavy metals by mass spectrometric analysis of ionized atoms after microwave digestion. |
| Chloride Ion Impurity | Ion Chromatography | Separates and quantifies chloride anions using ion-exchange column and conductivity detection. |
| Appearance (Color & Clarity) | Visual Inspection | Assesses physical state, color (e.g., white to off-white powder), and solution clarity against standard references. |
| Sulfur Content | Elemental Analyzer (Combustion Method) | Determines total sulfur by high-temperature combustion followed by infrared detection of SO2. |
