Manufacturing Quality Control of (ETHYLENEDINITRILO)TETRAACETIC ACID, TRISODIUM SALT HYDRATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (EDTA trisodium salt) | Complexometric titration with standardized ZnSO4 or CuSO4 solution | Based on stoichiometric 1:1 complex formation between EDTA and metal ion at controlled pH, using Eriochrome Black T or Calmagite indicator. |
| pH (1% aqueous solution) | Potentiometric pH measurement | Determination of hydrogen ion activity using calibrated glass electrode and reference electrode in a 1% w/v aqueous solution. |
| Loss on drying (LOD) | Gravimetric method at 105 C | Mass loss measured after drying sample to constant weight at 105 C, reflecting water and volatile impurities. |
| Heavy metals (as Pb) | Colorimetric sulfide precipitation with visual comparison | Reaction with thioacetamide under buffered conditions to form colored metal sulfides; compared against lead standard. |
| Chloride | Potentiometric titration with AgNO3 | Precipitation of chloride as AgCl monitored by silver ion-selective electrode or potentiometric endpoint detection. |
| Sulfate | Gravimetric analysis as BaSO4 | Precipitation as barium sulfate in acidic medium followed by filtration, drying, and weighing. |
| Iron (Fe) | UV-Vis spectrophotometry with 1,10-phenanthroline | Formation of orange-red Fe(II)-phenanthroline complex measured at ~510 nm after reduction with hydroxylamine. |
| Lead (Pb) | ICP-OES | Quantification via atomic emission intensity of characteristic Pb wavelengths (e.g., 220.353 nm) after acid digestion and plasma excitation. |
| Arsenic (As) | Hydride generation AAS (HG-AAS) | Reduction of As to arsine gas, swept into quartz cell for atomic absorption measurement at 193.7 nm. |
| Residue on ignition | Gravimetric method at 500-600 C | Mass of non-volatile inorganic residue remaining after high-temperature ashing. |
| Appearance (color and clarity) | Visual inspection in aqueous solution | Assessment of color (vs. platinum-cobalt scale) and absence of suspended particles in a clear 5% w/v solution. |
| Microbial contamination | Membrane filtration and colony count | Enumeration of aerobic mesophilic microorganisms after filtration, membrane transfer to agar media, and incubation. |
