Industrial Applications of ETHYLENEDIAMINETETRAACETIC ACID DISODIU&
| Industry | Application | Process |
|---|---|---|
| Food Industry | Used as a nutritional fortificant to supplement zinc and prevent zinc deficiency | Directly incorporated into fortified foods (e.g., cereals, dairy products) during food processing; forms a stable complex with sodium zinc ethylenediaminetetraacetate to enhance zinc bioavailability |
| Pharmaceutical Industry | Used in the treatment of zinc deficiency and as an adjunct to support immune function | Serves as a zinc source in oral or injectable formulations; the chelated form improves zinc absorption and stability while minimizing gastrointestinal irritation |
| Animal Nutrition | Used as a feed additive to supply essential zinc to animals | Incorporated into feed production by blending with other nutrients, followed by pelleting or spray application to ensure uniform distribution and improved zinc absorption and stability |
| Cosmetics Industry | Used as a stabilizer and trace nutrient to support skin health | Added to emulsions, creams, and similar products; its chelating stability prevents metal-catalyzed oxidation, while enabling controlled release of zinc ions |
| Agriculture | Used as a component of foliar or water-soluble fertilizers to supply zinc to crops | Dissolved in water and applied via foliar spraying or irrigation; the EDTA–zinc complex enhances zinc availability in alkaline soils |
Manufacturing Quality Control of ETHYLENEDIAMINETETRAACETIC ACID DISODIU&
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (EDTA·2Na·Zn content) | Complexometric Titration with EDTA standard solution | Zinc is quantitatively displaced by excess standardized EDTA under controlled pH, and back-titrated with zinc sulfate or copper sulfate solution using xylenol orange indicator. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS or ICP-OES | Sample digested in acid matrix; elemental concentrations determined by mass spectrometry or optical emission detection after plasma ionization. |
| Loss on Drying (LOD) | Gravimetric Analysis (Thermogravimetry) | Mass loss measured after drying at 105 °C to constant weight, reflecting volatile content including water and residual solvents. |
| pH (1% aqueous solution) | Potentiometric pH Measurement | Hydrogen ion activity measured using calibrated glass electrode in a 1% w/v aqueous solution at 25 °C. |
| Chloride Impurity | Ion Chromatography (IC) or Potentiometric Titration with AgNO₃ | Chloride ions separated and quantified by conductivity detection (IC) or titrated with silver nitrate using potentiometric endpoint detection. |
| Sulfate Impurity | Barium Sulfate Gravimetric Method or IC | Sulfate precipitated as BaSO₄ under acidic conditions and weighed; or separated and quantified by ion chromatography with conductivity detection. |
| Residue on Ignition | Gravimetric Ashing | Inorganic residue mass determined after ignition at 500–600 °C, indicating non-volatile inorganic impurities. |
| Appearance and Color | Visual Inspection against Standard Solutions (e.g., APHA/Hazen scale) | Subjective assessment of clarity and color intensity in aqueous solution compared to platinum-cobalt reference standards. |
| Zinc Content | Atomic Absorption Spectroscopy (AAS) or ICP-OES | Zinc atoms in atomized sample absorb or emit characteristic wavelength radiation, enabling quantitative determination based on calibration curve. |
| Free EDTA Content | Reverse Phase HPLC with UV Detection | Separation of free EDTA from chelated form using C18 column and UV detection at ~200 nm; quantification via external standard calibration. |
| Microbial Contamination | Membrane Filtration followed by TSA/SDA Culture | Sample filtered through sterile membrane; filter placed on Tryptic Soy Agar (TSA) and Sabouraud Dextrose Agar (SDA), incubated for aerobic bacteria and fungi enumeration. |
| Particle Size Distribution | Laser Diffraction Particle Size Analysis | Scattering pattern of laser beam passing through dispersed sample is analyzed to determine volume-based particle size distribution. |
| Water Content (Karl Fischer) | Volumetric or Coulometric Karl Fischer Titration | Iodine generated electrochemically (coulometric) or added volumetrically reacts stoichiometrically with water; endpoint detected amperometrically. |
| Specific Optical Rotation | Polarimetry | Rotation of plane-polarized light measured in solution at specified concentration, temperature, and wavelength (e.g., sodium D-line, 589 nm). |
