Manufacturing Quality Control of Calcium bromide
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Place the sample on a white background and observe its color, physical state, and presence of mechanical impurities. The product should be white crystals or powder, free from visible foreign matter. |
| Main Content (Purity of CaBr₂) | Argentometric Method (Precipitation Titration) | Titrate bromide ions with standard silver nitrate solution to form silver bromide precipitate. The endpoint is determined by potentiometry or an indicator (e.g., fluorescein), and the CaBr₂ content is calculated accordingly. |
| Chlorides | Nephelometric Method with Silver Nitrate | In a nitric acid medium, chloride ions react with silver nitrate to form turbidity due to silver chloride. The turbidity is compared with a standard series to determine the chloride limit. |
| Heavy Metals | Sulfide Colorimetric Method (e.g., for Lead) | In weakly acidic conditions, heavy metal ions react with hydrogen sulfide to form colored sulfide precipitates, which are compared visually with a standard lead solution for quantification. |
| pH Value | pH Meter Method | Dissolve the calcium bromide sample in water to a specified concentration and measure the pH directly using a calibrated pH meter. The pH is typically required to be between 4.0 and 8.0. |
| Loss on Drying | Gravimetric Method (Drying to Constant Weight) | Dry the sample in an oven at 105°C until constant weight is achieved. The weight loss is used to calculate the content of moisture and volatile substances. |
| Residue on Ignition | Ignition Method (Gravimetric Analysis) | Ignite the sample at high temperature (approximately 600–800°C) to decompose organic matter, then weigh the remaining inorganic residue to assess non-volatile impurities. |
| Calcium Content | EDTA Complexometric Titration | In alkaline conditions, titrate calcium ions with standard EDTA solution using a calcium indicator (e.g., calcon carboxylic acid) to detect the endpoint, indirectly verifying the CaBr₂ content. |
| Arsenic Content | Gutzeit Method or Atomic Absorption Spectroscopy (AAS) | Gutzeit Method: Arsine gas reacts with mercuric bromide paper to produce a colored stain; AAS offers higher sensitivity and enables quantitative determination of trace arsenic. |
| Iron Content | Spectrophotometric Method with Thiocyanate or AAS | Iron ions form a red complex with potassium thiocyanate, which is measured colorimetrically; AAS provides higher accuracy and is suitable for determining low iron concentrations. |
