Industrial Applications of EDTA calcium disodium
| Industry | Application | Process |
|---|---|---|
| Chemical | Chelating agent to eliminate interference from metal ions | Synthesized via reaction of ethylenediamine with chloroacetic acid to produce ethylenediaminetetraacetic acid (EDTA), followed by reaction with sodium hydroxide and calcium chloride to form disodium calcium EDTA |
| Water Treatment | Removal of heavy metal ions in water treatment | Forms stable complexes with metal ions present in water, thereby facilitating their removal |
| Dyeing & Printing | Chelating agent in textile processing | Reacts with metal ions during dyeing to prevent adverse effects on dyes |
| Pharmaceuticals | Stabilizer in certain drug formulations | Acts as an auxiliary component by binding metal ions in the drug formulation to enhance stability |
| Food | Food additive to prevent metal ion–induced spoilage | Binds metal ions in food to inhibit metal-catalyzed oxidation reactions |
Manufacturing Quality Control of EDTA calcium disodium
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Identification Test | Infrared Spectroscopy (IR) | By comparing the infrared absorption spectrum of the sample with that of the reference standard, confirm whether the chemical structure characteristics are consistent. |
| Calcium Ion Color Reaction | Add reagents such as ammonium oxalate or sulfuric acid, and observe if a white precipitate (calcium oxalate) is formed to verify the presence of calcium ions. | |
| Content Determination | Complexometric Titration (EDTA Back Titration) | At pH ≈ 10, using chrome black T as an indicator, titrate excess EDTA with zinc standard solution to calculate the content of the main component. |
| High-Performance Liquid Chromatography (HPLC) | Use ion-pair or reversed-phase chromatographic columns with ultraviolet detection for quantitative analysis of the main component, suitable for high-purity samples. | |
| pH Value | pH Meter Measurement | Prepare a solution of a certain concentration (e.g., 1%), and directly measure the acidity or alkalinity with a calibrated pH meter. |
| Solution Clarity and Color | Visual Colorimetry / Spectrophotometry | Compare with standard turbidity solutions or standard color solutions to evaluate whether the solution is clear and free of abnormal color. |
| Drying Loss | Drying to Constant Weight | Dry the sample at 105°C until constant weight is achieved, and calculate the percentage of mass loss to reflect moisture and volatile substance content. |
| Heavy Metals | Sulfuric Acetamide Method (Chinese Pharmacopoeia Method) | React with sulfuric acetamide under weak acidic conditions to produce color, and compare with lead standard solution to control total heavy metal content. |
| Chlorides | Silver Nitrate Turbidity Method | Generate silver chloride turbidity by reacting in nitric acid medium with AgNO₃, and compare with standard Cl⁻ solution to determine limit. |
| Sulfates | Barium Chloride Turbidity Method | Generate barium sulfate precipitate by reacting in hydrochloric acid medium with BaCl₂, and compare with standard SO₄²⁻ solution to determine turbidity. |
| Iron Salts | Thiocyanate Colorimetric Method | React with ammonium thiocyanate in hydrochloric acid medium to form red complexes, and compare with standard iron solution for colorimetric determination. |
| Related Substances/Impurities | High-Performance Liquid Chromatography (HPLC) | Separate potential impurities (such as free EDTA, sodium salts, degradation products, etc.) using gradient elution or isocratic elution. |
| Bacterial Endotoxins | LAL Method (Limulus Amebocyte Lysate) | Use lysate from horseshoe crab blood cells to detect endotoxins through coagulation reaction, and quantitatively or semi-quantitatively detect pyrogenic substances. |
| Microbial Limit | Plate Count Method / Membrane Filtration Method | According to pharmacopoeia regulations, inoculate culture media and count the total number of aerobic bacteria, mold, and yeast to control microbial contamination. |
| Calcium Content | Atomic Absorption Spectrophotometry (AAS) | Determine the absorbance of calcium element at a specific wavelength (e.g., 422.7 nm) after atomizing the sample, and calculate its content. |
| Sodium Content | Flame Photometry / ICP-OES | Determine the content of sodium element by measuring the characteristic spectral emission (589 nm) of sodium atoms excited in a flame, or by using an ICP instrument. |
