Manufacturing Quality Control of Manganese disodium EDTA trihydrate
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Main Content (EDTA-Mn Complex) | Complexometric Titration (EDTA Back Titration) | Excess EDTA is back-titrated with standard zinc or copper solution in a pH 5–6 buffer solution, using xylenol orange as indicator. The main content is calculated based on the volume of standard solution consumed. |
| Manganese (Mn) Content | Atomic Absorption Spectroscopy (AAS) or Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) | After acid digestion, manganese is determined by measuring the intensity of its characteristic spectral line at 539.5 nm (AAS) or 257.6 nm (ICP-OES), quantified via calibration curves. |
| Moisture Content | Karl Fischer Titration | The Karl Fischer reagent (containing iodine, sulfur dioxide, pyridine, and methanol) reacts quantitatively with water. The water content is determined by potentiometric or endpoint indication method. |
| Chloride (Cl⁻) | Silver Nitrate Titration (Mohr’s Method or Potentiometric Titration) | Chloride ions are titrated with standardized silver nitrate solution under neutral or slightly alkaline conditions, using potassium chromate as indicator (Mohr’s method) or detecting potential change (potentiometric method) to determine the endpoint. |
| Sulfate (SO₄²⁻) | Turbidimetry (Barium Chloride Precipitation Method) | After sample acidification, barium chloride solution is added to form barium sulfate precipitate. Turbidity is measured spectrophotometrically at 420 nm and compared with a standard series for sulfate content determination. |
| pH Value | Glass Electrode Method (pH Meter) | The sample is dissolved in water to a specified concentration, and the pH is directly measured using a calibrated pH meter. The value should be within the range of 5.0–7.5 (according to pharmacopeial or company specifications). |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) or Thiourea Colorimetric Method | After sample treatment, lead is reacted with thiourea in a pH 3.5 buffer to form a colored sulfide complex, which is compared visually with a standard lead solution; alternatively, AAS is used for direct lead quantification. |
| Iron (Fe) Content | Orthophenanthroline Spectrophotometry | After acid digestion, Fe²⁺ forms an orange-red complex with orthophenanthroline. The absorbance is measured at 510 nm and quantified by comparison with a standard curve. |
| Drying Loss | Gravimetric Drying Method | The sample is dried at 105°C until constant weight. The loss in mass percentage is calculated to assess total volatile impurities and moisture content. |
| Appearance and Color | Visual Inspection | Observe that the sample appears as pale pink or light purple crystalline powder, free from visible foreign particles, lumps, or discoloration, meeting pharmaceutical-grade or food-grade appearance requirements. |
| Solubility | Physical Dissolution Test | Sample is added to water in a specified ratio and stirred. Complete dissolution should occur; insoluble residue must comply with specified limits. |
| Purity (HPLC, Optional) | High-Performance Liquid Chromatography (HPLC) | Using a C18 column, a buffer-salt/methanol mobile phase, and UV detection (210–220 nm), the main peak of EDTA-Mn is detected. Purity is calculated from peak area, excluding impurity peaks. |
