Manufacturing Quality Control of Naphthalene-1,3,5-trisulphonic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies sulfonic acid groups via neutralization with standardized NaOH solution using phenolphthalein indicator. |
| Moisture Content | Karl Fischer Titration | Determines water content by coulometric or volumetric reaction of iodine with water in a methanol-based electrolyte. |
| pH (1% aqueous solution) | pH Meter Measurement | Measures hydrogen ion activity in a standardized aqueous solution using calibrated glass electrode. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metal content after acid digestion by measuring absorbance of ground-state atoms at characteristic wavelengths. |
| Sulfate Impurity | Ion Chromatography (IC) | Separates and quantifies sulfate anions based on differential retention on anion-exchange column with conductivity detection. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Detects chloride via precipitation titration using silver nitrate and silver/silver chloride reference electrode. |
| Iron Content | ICP-OES | Measures Fe emission intensity after microwave-assisted acid digestion and plasma atomization/excitation. |
| Color (APHA) | UV-Vis Spectrophotometry | Evaluates yellowness by comparing absorbance at 430 nm against platinum-cobalt standard solutions. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature incineration followed by precise weighing of residual solids. |
| Organic Impurities (Related Substances) | HPLC with UV Detection | Separates and quantifies structurally related aromatic sulfonates using reversed-phase C18 column and UV absorbance at 254 nm. |
| Bulk Density | Tap Density Measurement | Determines mass per unit volume after controlled tapping of sample in a graduated cylinder per ASTM D1895. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution by analyzing angular variation in laser light scattering from dispersed particles in air or liquid medium. |
