Manufacturing Quality Control of Nitroterephthalic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, based on peak area comparison against a certified reference standard. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content via reaction of iodine with sulfur dioxide in a methanol-based solvent system. |
| Residue on Ignition | Gravimetric Analysis | Determination of inorganic ash content by high-temperature incineration followed by weighing of residual non-volatile matter. |
| Heavy Metals (as Pb) | AAS | Atomic absorption spectroscopy after acid digestion to quantify total heavy metals, reported as lead equivalent. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column with suppressed conductivity detection. |
| Sulfate Impurity | Gravimetric Analysis | Precipitation of sulfate as barium sulfate under acidic conditions, followed by filtration and weighing of dried precipitate. |
| Iron Content | AAS | Flame atomic absorption spectroscopy after sample dissolution and matrix-matching calibration for iron quantification. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Measurement of yellowness intensity by comparing sample solution color to APHA platinum-cobalt standard solutions or using spectrophotometric absorbance at 430 nm. |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination of solid-to-liquid transition temperature range using calibrated capillary tube method. |
| Organic Volatile Impurities | GC-FID | Gas chromatographic separation with flame ionization detection to identify and quantify residual solvents and low-boiling impurities. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample using light scattering principles to determine volume-based particle size distribution. |
| pH of Aqueous Suspension | pH Meter | Measurement of hydrogen ion activity in a defined aqueous suspension (e.g., 1% w/v) using calibrated pH electrode. |
