Manufacturing Quality Control of Cadmium iodide
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color and physical state of the sample under natural light to determine if it is a white or slightly yellow crystalline powder, checking for impurities, caking, etc. |
| Assay (Purity of CdI₂) | Argentometric Titration (Precipitation Titration) | The iodide ions react with silver nitrate to form silver iodide precipitate. The endpoint is determined by potentiometric detection or an indicator (e.g., fluorescein). Total iodine content is calculated and CdI₂ purity is deduced indirectly. |
| Total Heavy Metals (Cadmium Content) | Atomic Absorption Spectroscopy (AAS) or Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | After dissolving the sample, cadmium content is measured using AAS or ICP-OES to verify consistency with theoretical values and assess the main component concentration. |
| Moisture (Loss on Drying) | Thermogravimetric Analysis (TGA) or Oven Drying Method | Heat the sample at a specified temperature (e.g., 105°C) for a certain period, then calculate moisture or volatile content based on weight difference before and after drying. Suitable for assessing crystallization or adsorbed water. |
| Chloride Impurities | Turbidimetric Method with Silver Nitrate | Add silver nitrate to the sample solution in a nitric acid medium and observe whether a white turbidity (AgCl) forms. Compare with a standard chloride solution to assess chloride residue. |
| Sulfate Impurities | Turbidimetric Method | Add barium chloride to the sample in hydrochloric acid medium and observe formation of white precipitate (BaSO₄). Compare turbidity with a standard sulfate solution. |
| Iron Impurities | Spectrophotometric Method with Thiocyanate | In acidic conditions, iron ions react with ammonium thiocyanate to form a red complex. The absorbance is measured at 480 nm using a spectrophotometer to quantify iron content. |
| Heavy Metals (e.g., Lead, Copper) | Atomic Absorption Spectroscopy (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | After sample digestion, use AAS or the more sensitive ICP-MS to measure trace levels of multiple heavy metal impurities, ensuring compliance with pharmacopeial or industrial standards. |
| pH Value (Solution) | pH Meter Measurement | Prepare an aqueous solution of defined concentration (e.g., 5% w/v), measure pH using a calibrated pH meter to evaluate whether the solution is neutral or weakly acidic. |
| Insoluble Impurities | Residue by Filtration and Gravimetry | Dissolve the sample in water or ethanol, filter the insoluble residue, dry, weigh, and calculate the percentage of insoluble matter. |
