Manufacturing Quality Control of Potassium bromide
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Assay | Argentometric Method (Precipitation Titration) | Titrates bromide ions using a standard silver nitrate solution, forming silver bromide precipitate. The endpoint is determined by potentiometry or an indicator (e.g., potassium chromate), and the KBr content is calculated accordingly. |
| Bromide Ion (Br⁻) | Ion Chromatography (IC) | Separates bromide ions using an ion-exchange column and detects them via conductivity detector; suitable for trace impurity analysis and quantitative determination of the main component. |
| Chloride Impurity | Turbidimetric Method with Silver Nitrate | In acidic conditions, silver nitrate is added to form a white turbidity from chlorides. The turbidity is compared with a standard chloride solution to determine the limit. |
| Sulfate Impurity | Barium Sulfate Turbidimetric Method | In hydrochloric acid medium, barium chloride is added to form white barium sulfate turbidity. The turbidity is compared against a standard solution for limit testing. |
| Loss on Drying | Thermogravimetric Analysis (or Oven Method) | The sample is dried at 105°C to constant weight, and the weight loss is used to calculate the content of moisture and volatile substances. |
| Residue on Ignition | Residue on Ignition Test | The sample is ignited at high temperature, and the residue is weighed to determine the total amount of inorganic impurities. |
| Heavy Metals | Thioacetamide Method (Pharmacopoeia Method) | In weakly acidic conditions, heavy metals react with thioacetamide to form colored sulfides. The color intensity is compared visually with a standard lead solution for limit testing. |
| pH Value | pH Meter Method | Aqueous solution of KBr (typically 5%) is prepared and the pH is directly measured using a pH meter to control the acidity or alkalinity of the product. |
| Clarity | Visual Turbidity Comparison Method | The sample is dissolved in water and the solution is observed for clarity. It is compared with a standard turbidity solution to assess the level of insoluble impurities. |
| Ammonium Salts | Nessler's Reagent Method | Ammonium ions react with Nessler's reagent to form a yellow or reddish-brown precipitate. The color is compared with a standard ammonium solution for limit testing. |
