Manufacturing Quality Control of Ethylenediaminetetraacetic acid tetrasodium salt
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color and state of the sample under natural light or standard light sources. It should be a white crystalline powder with no visible foreign matter. |
| Identification Test | Infrared Spectroscopy (IR) | Compare the sample's spectrum with a reference spectrum to confirm its molecular structure features, used for compound identification. |
| Conductivity Method / Ion Reaction Method | Utilize its property of dissociating into Na⁺ and EDTA⁴⁻ in water, detect sodium ions or chelation ability for auxiliary identification. | |
| Content Determination | Complexometric Titration | In pH 10 buffer solution, use Eriochrome Black T as an indicator and back-titrate with standard zinc or magnesium solution to calculate the EDTA disodium content. |
| High-Performance Liquid Chromatography (HPLC) | Use ion exchange or reverse-phase chromatography columns to detect the main component peak area, quantitative using external standard or internal standard method, high accuracy. | |
| pH Value | pH Meter Method | Prepare a sample solution at a certain concentration (e.g., 1% aqueous solution), measure the pH value with a calibrated pH meter; typically ranges from 7.0–9.0. |
| Water Content (Crystallization Water + Moisture) | Karl Fischer Titration Method | Use coulometric or volumetric Karl Fischer titration to accurately determine total water content, including crystallization water and adsorbed water. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Method | Dry the sample at specified temperature (e.g., 105°C) until constant weight is achieved, calculate the weight loss percentage to evaluate crystallization water and volatile substances content. |
| Residue on Ignition (Sulfate Ash) | Gravimetric Method | Igonize the sample at high temperature, add sulfuric acid treatment and re-ignite, weigh the residue to assess inorganic impurity content. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Digest the sample and measure the content of heavy metals such as lead, cadmium, mercury, and arsenic, ensuring compliance with pharmacopoeia or industry limits. |
| Chloride | Silver Nitrate Turbidity Method | Add silver nitrate in nitric acid medium to form silver chloride turbidity, compare with standard series to control chloride ion impurities. |
| Sulfate | Barium Chloride Turbidity Method | Add barium chloride in hydrochloric acid medium to form barium sulfate turbidity, compare with standard series to control sulfate root impurities. |
| Microbial Limit | Microbial Culture Method | Perform aerobic bacteria, mold, yeast count, and controlled bacterial (e.g., Escherichia coli) testing according to the Chinese Pharmacopoeia or ISO standards. |
