Manufacturing Quality Control of Sodium tetraborate
| Detection Item | Common Detection Methods | Method Overview |
|---|---|---|
| Assay | Acid-Base Titration (Mannitol Enhancement Method) | Utilizing the fact that boric acid is a weak acid and difficult to titrate directly, mannitol or other polyols are added to form a stable complex with boric acid, enhancing its acidity. The solution is then titrated with standard NaOH solution using phenolphthalein as the indicator to calculate the content of sodium tetraborate. |
| pH Value | pH Meter Method | Aqueous solution of sodium tetraborate at a specified concentration is prepared and its pH is measured directly using a calibrated pH meter, with the value controlled within the specified range (typically 9.0–9.6). |
| Chlorides | Silver Nitrate Turbidity Method | In nitric acid medium, chlorides react with silver nitrate to form a white turbidity of silver chloride, which is compared visually with a standard chloride turbidity solution to control impurity limits. |
| Sulfates | Barium Chloride Turbidity Method | In hydrochloric acid medium, sulfates react with barium chloride to form a white precipitate of barium sulfate, which is compared visually with a standard sulfate turbidity solution to assess sulfate impurity content. |
| Heavy Metals | Thioacetamide Method (or Atomic Absorption Spectrometry) | Under weakly acidic conditions, heavy metal ions react with thioacetamide to form colored sulfides for colorimetric quantification; alternatively, atomic absorption spectrometry may be used for precise determination of heavy metals such as lead and cadmium. |
| Arsenic Content | Goossens Method or Hydride Generation-Atomic Fluorescence Spectrometry | Goossens method: Metal zinc reacts with acid to generate nascent hydrogen, which reacts with arsenic compounds to form arsine gas that turns a bromide-mercury test paper colored; modern methods typically employ hydride generation-atomic fluorescence spectrometry, offering higher sensitivity and accuracy. |
| Drying Loss | Drying Method (Gravimetric) | The sample is dried at 105°C until constant weight is achieved; the weight loss is used to calculate the content of water and water of crystallization, with drying loss controlled within a specified range (e.g., 32.0%–37.0%). |
| Residue on Ignition (Ashing Residue) | Ignition Method | The sample is incinerated at high temperature (approximately 800°C) until constant weight is reached, and the total amount of non-volatile inorganic impurities is measured and calculated in terms of sulfate equivalent. |
| Ammonium Salts | Nessler’s Reagent Colorimetric Method | Ammonium ions release ammonia gas under alkaline conditions, which reacts with Nessler’s reagent (K₂HgI₄) to form a reddish-brown precipitate; the concentration is determined by colorimetry. |
| Sodium Ion (Auxiliary Verification) | Flame Photometry or Atomic Absorption Spectrometry | Sodium content is determined using a flame photometer or atomic absorption spectrometer to verify stoichiometric ratios or assist in purity analysis. |
