Industrial Applications of Zinc disodium EDTA
| Industry | Application | Process |
|---|---|---|
| Food Industry | Used as a nutritional fortificant to supplement zinc and prevent zinc deficiency | Added in stable chelated form to food additives for fortification of cereals, dairy products, and nutritional beverages |
| Pharmaceutical Industry | Used to treat zinc deficiency and as an adjunct chelating agent for heavy metal poisoning | Administered via intravenous injection or oral dosing; leverages controlled zinc ion release to maintain systemic zinc homeostasis |
| Agriculture | Formulated as a zinc fertilizer component to enhance plant zinc uptake efficiency | Applied as a chelated zinc source via foliar spray or soil application to improve crop stress tolerance and yield |
| Cosmetics Industry | Used as an antioxidant stabilizer and trace nutrient supplement | Incorporated into skincare formulations as a stable zinc carrier for oil control, anti-inflammatory action, and skin repair |
| Water Treatment | Used as a slow-release zinc source to inhibit microbial growth and corrosion | Slowly releases zinc ions in recirculating cooling water systems to form protective films that suppress metal corrosion |
Manufacturing Quality Control of Zinc disodium EDTA
| Test Item | Common Testing Methods | Method Summary |
|---|---|---|
| Appearance | Visual Inspection | Observe the color and physical state of the sample under natural or standard lighting; it should appear as white or off-white crystalline powder. |
| Identification | Infrared Spectroscopy (IR) | Compare the sample's spectrum with a reference standard; the main functional group absorption peaks should match to confirm molecular structure. |
| Metal Ion Reaction Test | Preliminary identification based on precipitation formed when zinc ions react with specific reagents (e.g., potassium ferrocyanide). | |
| Assay (Main Component) | Complexometric Titration (EDTA Titration) | In a buffer solution at pH ≈ 10, use Eriochrome Black T as indicator and back-titrate excess zinc ions with standardized EDTA solution to calculate content. |
| Atomic Absorption Spectrophotometry (AAS) | Dissolve the sample and measure zinc content at a specific wavelength (213.8 nm), then convert to active ingredient content. | |
| UV-Visible Spectrophotometry (Indirect Method) | Determine zinc content via color-forming reaction (e.g., complexation with dithizone); suitable for low-concentration detection. | |
| Moisture (Loss on Drying) | Karl Fischer Titration | Precisely determine total water content (free and bound water); suitable for hydrate-containing samples. |
| Loss on Drying (Oven Method) | Dry the sample at 105°C until constant weight; calculate moisture content from weight loss, taking care to avoid decomposition. | |
| Residue on Ignition | Residue on Ignition Test | Ignite the sample at high temperature (500–600°C), then weigh the residue to estimate inorganic impurity levels. |
| Heavy Metals | Sulfide Colorimetry (Chinese Pharmacopoeia Method) | In mildly acidic conditions, heavy metals react with hydrogen sulfide to form colored precipitates, which are compared to a standard lead solution for quantification. |
| Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | High-sensitivity determination of multiple heavy metals (e.g., Pb, As, Cd, Hg); suitable for high-purity materials. | |
| pH Value | pH Meter Method | Prepare a solution of defined concentration (e.g., 1% w/v), then measure pH using a calibrated pH meter. |
| Clarity and Solution Color | Visual Color Comparison | Dissolve the sample in water and compare against standard turbidity and color solutions to assess clarity and colorlessness. |
| Sulfate | Turbidimetry | In dilute hydrochloric acid medium, add barium chloride to form barium sulfate turbidity; quantify by comparison with a standard sulfate solution. |
| Chloride | Turbidimetry | Add silver nitrate to form silver chloride turbidity; measure by comparison with a standard chloride solution. |
| Microbial Limits | Microbial Limit Test (Pharmacopoeia Method) | Test for total aerobic microbial count, molds and yeasts, and specified pathogens (e.g., Escherichia coli, Salmonella spp.). |
