Industrial Applications of EDTA magnesium disodium
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Antidote (for heavy metal poisoning) | Administered intravenously to chelate excess metal ions (e.g., lead, cadmium) in the body, forming stable complexes that are excreted via urine |
| Analytical Chemistry | Reagent for metal ion titration analysis | Used as a standard chelating reagent in complexometric titrations to determine concentrations of metal ions such as calcium and magnesium in water samples or solutions |
| Water Treatment | Water softening and metal ion stabilization | Added to recirculating cooling water systems to prevent metal ion precipitation and scale formation, and to inhibit metal-catalyzed oxidation reactions |
| Consumer Chemicals | Cosmetic additive (stabilizer) | Incorporated into skincare products, shampoos, and other formulations to chelate metal ions in water, preventing degradation of active ingredients and enhancing product stability |
| Textile Industry | Dyeing and finishing auxiliary | Applied as a chelating agent during dyeing to eliminate adverse effects of metal ions in water on dyes, improving dye uniformity and color fastness |
| Agriculture | Micronutrient fertilizer additive | Complexed with nutrients such as magnesium to enhance plant nutrient uptake efficiency and prevent nutrient fixation by metal ions in soil |
Manufacturing Quality Control of EDTA magnesium disodium
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color and physical state of the sample under natural or standard lighting to determine if it is a white crystalline powder and check for visible foreign matter. |
| Identification | Infrared Spectroscopy (IR) | Compare the sample spectrum with a reference standard; confirm molecular structure through characteristic absorption peaks to verify authenticity. |
| Complexometric Titration | Utilize the chelating properties of EDTA with metal ions; titrate with a standard zinc or calcium solution at a specific pH to confirm chelating capability. | |
| Assay | Complexometric Titration (e.g., titration with zinc standard solution) | In a pH 10 buffer, use Eriochrome Black T as indicator and titrate excess magnesium ions with standard zinc solution to calculate the content of EDTA magnesium. |
| Moisture (Loss on Drying) | Oven Drying Method (Thermogravimetric Analysis or Oven Method) | Dry the sample at 105°C until constant weight; calculate moisture content based on weight loss. Typically requires ≤8.5%. |
| pH Value | pH Meter Method | Prepare a certain concentration of solution (e.g., 1% aqueous solution) and measure its acidity or alkalinity using a calibrated pH meter. Acceptable range is generally 5.0–7.0. |
| Heavy Metals | Sulfide Colorimetry (e.g., Chinese Pharmacopoeia method) | In acidic conditions, heavy metals react with hydrogen sulfide to form colored precipitates. Compare color intensity with a standard lead solution to control limits. |
| Chlorides | Silver Nitrate Turbidimetry | Chloride ions in the sample react with silver nitrate to form a turbid suspension of silver chloride. Compare turbidity against a standard chloride solution to control impurity levels. |
| Sulfates | Barium Chloride Turbidimetry | Sulfate ions react with barium chloride to form a barium sulfate precipitate. Use turbidimetry to compare against a standard sulfate solution and control sulfate impurities. |
| Residue on Ignition | Ignition Method | Ignite the sample at high temperature (approximately 600–800°C) to constant weight and measure the total amount of non-volatile inorganic impurities. Typically requires ≤0.3%. |
| Microbial Limits | Microbial Limit Test (Pharmacopoeial Method) | Perform tests according to the Chinese Pharmacopoeia or relevant standards for total aerobic microbial count, mold and yeast count, and specified microorganisms. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase column with UV detection to identify impurity peaks other than the main peak, assessing purity and individual/total impurity levels. |
