Manufacturing Quality Control of Copper citrate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Cu content) | Complexometric Titration with EDTA | Copper ions form a stable complex with EDTA at pH 10; endpoint detected using murexide indicator. |
| Assay (Citric acid content) | Acid-Base Titration with NaOH | Citric acid is titrated with standardized NaOH using phenolphthalein; total acidity reflects citrate content. |
| Loss on Drying | Gravimetric Analysis (Thermogravimetry) | Sample is dried at 105 C to constant weight; mass loss indicates volatile components and moisture. |
| Water Content (Karl Fischer) | Coulometric Karl Fischer Titration | Iodine generated electrochemically reacts stoichiometrically with water; quantifies trace water content. |
| Heavy Metals (Pb, Cd, As, Hg) | ICP-MS | Multi-element detection via ionization in plasma and mass separation; provides ultra-trace heavy metal quantification. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Chloride ions react with silver nitrate; endpoint detected by silver electrode potential shift. |
| Sulfate Impurity | Barium Sulfate Gravimetric Method | Sulfate precipitated as BaSO4 under controlled conditions; dried and weighed for quantification. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Hydrogen ion activity measured using calibrated glass electrode in 1% w/v aqueous suspension. |
| Insoluble Matter | Filtering and Gravimetry | Sample dissolved in water, filtered through pre-weighed sintered glass crucible, dried and weighed. |
| Iron Impurity | UV-Vis Spectrophotometry (1,10-Phenanthroline) | Fe2+ forms orange-red complex with 1,10-phenanthroline; absorbance measured at 510 nm. |
| Arsenic | Silver Diethyldithiocarbamate (SDDC) Method | Arsenic hydride reacts with SDDC to form red-colored complex; measured spectrophotometrically at 540 nm. |
| Residue on Ignition | Gravimetric Analysis (Ignition at 600 C) | Non-volatile residue determined after ignition at 600 C; indicates inorganic impurities and ash content. |
