Manufacturing Quality Control of DISODIUM TEREPHTHALATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Na2TPA content) | Acid-base titration | Quantifies Na2TPA by back-titration with standardized HCl after alkaline hydrolysis. |
| Sodium content | Flame photometry | Measures Na+ emission intensity at 589 nm in atomized sample solution. |
| Chloride impurity | Potentiometric titration with AgNO3 | Determines Cl- concentration via precipitation titration using silver nitrate and Ag electrode. |
| Sulfate impurity | Gravimetric analysis | Precipitates SO4(2-) as BaSO4, followed by drying and weighing of the precipitate. |
| Heavy metals (Pb, Cd, Ni, etc.) | ICP-OES | Simultaneously quantifies trace metals by measuring element-specific atomic emission intensities. |
| Loss on drying | Thermogravimetric analysis (TGA) | Measures mass loss upon heating to 105 C for 2 h under controlled atmosphere. |
| pH of aqueous solution (1% w/v) | pH meter measurement | Determines hydrogen ion activity in a standardized aqueous suspension at 25 C. |
| Iron impurity | UV-Vis spectrophotometry (with 1,10-phenanthroline) | Forms orange-red Fe(II)-phenanthroline complex; absorbance measured at ~510 nm. |
| Water insolubles | Filtration and gravimetry | Filters sample through pre-weighed sintered glass crucible, dries residue, and weighs. |
| Residue on ignition | Ignition at 600 C followed by gravimetry | Measures non-volatile inorganic residue after high-temperature ashing. |
| Color (APHA) | Visual comparison or spectrophotometric APHA scale | Evaluates yellowness/browning against platinum-cobalt standard solutions. |
| Particle size distribution | Laser diffraction | Determines size distribution by analyzing angular scattering pattern of laser beam passing through dispersed sample. |
