Manufacturing Quality Control of ETHYLENEDIAMINETETRAACETIC DIANHYDRIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (EDTA dianhydride content) | Acid-base titration with NaOH after hydrolysis | Hydrolysis converts dianhydride to EDTA, which is titrated with standardized NaOH using potentiometric or indicator endpoint detection. |
| Moisture content | Karl Fischer titration | Quantitative determination of water by reaction with iodine and sulfur dioxide in a methanol-based reagent under controlled conditions. |
| pH of aqueous solution (1% w/v) | pH meter measurement | Dissolution in deionized water followed by direct pH measurement using calibrated pH electrode. |
| Heavy metals (as Pb) | Atomic absorption spectroscopy (AAS) | Sample digestion followed by quantification of total heavy metals via flame or graphite furnace AAS at characteristic wavelengths. |
| Sulfated ash | Gravimetric analysis | Ignition of sample at 700-800 C followed by weighing of residual inorganic sulfate salts. |
| Chloride content | Ion chromatography (IC) | Separation and quantification of chloride ions using anion-exchange column and conductivity detection. |
| Residue on ignition | Gravimetric analysis | Heating sample to constant weight at 500-600 C and measuring non-volatile residue mass. |
| Appearance | Visual inspection | Assessment of physical state, color, and presence of visible particulates or discoloration against standard reference. |
| Melting point | Capillary melting point apparatus | Determination of temperature range at which solid transitions to liquid using calibrated capillary tube method. |
| Organic impurities (related substances) | High-performance liquid chromatography (HPLC) | Separation and quantification of impurities using reversed-phase C18 column and UV detection at 210 nm. |
| Iron content | Inductively coupled plasma optical emission spectrometry (ICP-OES) | Acid digestion followed by multi-element detection based on element-specific atomic emission lines. |
| Bulk density | Graduated cylinder method | Measurement of mass per unit volume for freely settled powder in standardized cylinder under defined tapping conditions. |
