Industrial Applications of Copper disodium EDTA
| Industry | Application | Process |
|---|---|---|
| Agriculture | As a micronutrient fertilizer to supply copper and iron essential for plant growth | Applied as a foliar spray after dissolution in water |
| Electroplating | Used as an additive in electroplating baths to improve coating uniformity and brightness | Mixed with other electroplating bath components |
| Chemical Manufacturing | Employed as a catalyst or stabilizer in organic synthesis reactions | Directly added to the reaction system |
| Water Treatment | Used for boiler water softening to prevent calcium and magnesium scale formation | Dosed in combination with other chelating agents |
| Pharmaceuticals | Acts as a metal ion chelator in certain disinfectant formulations | Incorporated into sprays or liquid solutions after formulation dissolution |
| Textile Dyeing and Printing | Functions as a mordant to enhance dye-fiber binding | Added to the dye bath during pretreatment |
| Analytical Chemistry | Serves as a standard reagent in EDTA titrations for metal ion determination | Prepared as a standardized solution in the laboratory |
Manufacturing Quality Control of Copper disodium EDTA
| 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 blue to bluish-green crystalline powder, checking for impurities, caking, etc. |
| Identification Test | UV-Visible Spectrophotometry (UV-Vis) | Qualitative identification based on the characteristic absorption peak of the Cu²⁺-EDTA complex at a specific wavelength (e.g., around 730 nm). |
| Infrared Spectroscopy (FTIR) | Confirm the presence of functional groups (such as carboxyl, amino, and Cu-N/O coordination bonds) by comparing with reference spectra. | |
| Assay | Complexometric Titration (Back Titration with EDTA) | Add excess standard Zn²⁺ or Pb²⁺ solution to the sample in a pH-buffered solution to displace Cu²⁺; then titrate the remaining metal ions with standard EDTA solution to indirectly calculate the EDTA-Cu content. |
| UV-Visible Spectrophotometry | Quantify concentration based on the absorbance of Cu-EDTA at a specific wavelength using a calibration curve. | |
| Loss on Drying (Moisture Content) | Thermogravimetric Analysis (TGA) or Oven Drying Method | Dry the sample at 105°C until constant weight; calculate moisture content based on weight loss. |
| Chlorides | Silver Nitrate Turbidity Method | In a nitric acid medium, chloride ions react with Ag⁺ to form a white precipitate; turbidity is compared against a standard chloride solution for quantification. |
| Sulfates | Barium Chloride Turbidity Method | In a hydrochloric acid medium, sulfate ions react with Ba²⁺ to form a white precipitate; concentration is determined by turbidity comparison. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, determine lead and other heavy metal contents using AAS or ICP-MS to ensure compliance with pharmacopoeial or industry standards. |
| pH Value | pH Meter Method | Prepare a solution of specified concentration (e.g., 1% w/v), measure pH using a calibrated pH meter; typically should be between 6.0 and 8.0. |
| Sulfated Ash (Residue on Ignition) | Residue on Ignition Method | Ignite the sample at high temperature (500–600°C) until constant weight; the residue weight represents sulfated ash, indicating inorganic impurity levels. |
| Volatile Organic Impurities | Gas Chromatography (GC) | If organic solvents are used in the manufacturing process, GC can be used to detect residual solvents such as ethanol or acetone. |
| Microbial Limits | Microbial Limits Test (Pharmacopoeia Method) | Perform tests according to the Chinese Pharmacopoeia or relevant standards for total aerobic microbial count, molds and yeasts count, and specified pathogens (e.g., E. coli). |
