Manufacturing Quality Control of Tripotassium hydrogen ethylenediaminetetraacetate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (EDTA-K3 content) | Acid-base titration with CuSO4 | Complexometric titration using copper(II) sulfate standard solution at pH 5.5; endpoint detected by potentiometry or indicator (e.g., PAN). |
| pH (1% aqueous solution) | pH meter measurement | Electrometric determination of hydrogen ion activity in a 1% w/v aqueous solution at 25 C. |
| Heavy metals (as Pb) | Atomic absorption spectroscopy (AAS) | Quantification of total heavy metals after wet digestion, using lead as the reference metal and flame or graphite furnace AAS. |
| Iron (Fe) | Inductively coupled plasma optical emission spectrometry (ICP-OES) | Multi-element detection after acid digestion; Fe measured at characteristic emission wavelength (e.g., 238.204 nm). |
| Chloride (Cl-) | Potentiometric titration with AgNO3 | Titration with silver nitrate using a silver electrode; chloride forms insoluble AgCl precipitate. |
| Sulfate (SO4) | Gravimetric analysis | Precipitation as BaSO4 after acidification and addition of barium chloride; dried and weighed. |
| Loss on drying (LOD) | Thermogravimetric method | Mass loss measured after heating at 105 C for 2 hours under controlled humidity conditions. |
| Water content | Karl Fischer titration | Volumetric or coulometric determination based on stoichiometric reaction of water with iodine and sulfur dioxide in pyridine/methanol medium. |
| Residue on ignition | Gravimetric analysis | Mass of inorganic residue remaining after incineration at 600 C for 30 minutes. |
| Appearance | Visual inspection | Assessment of physical state, color, and absence of visible foreign particles or discoloration against white background. |
| Solubility | Qualitative dissolution test | Observation of complete dissolution in specified volume of water (e.g., 1 g in 5 mL H2O) within 5 minutes at 20 C. |
| Microbial limits | Membrane filtration and plate count | Enumeration of aerobic mesophilic bacteria and molds/yeasts on appropriate agar media after membrane filtration of solution. |
