Manufacturing Quality Control of Cobalt chloride hexahydrate
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color, crystal form, presence of clumping, impurities, or foreign matter. Hexahydrate cobalt chloride should appear as bright pink or rose-red crystals. |
| Moisture Content | Thermogravimetric Analysis (TGA) or Drying Loss Method | Dry the sample to constant weight at 105–110°C, measure the mass loss, and calculate the water content, which should be close to the theoretical value (~45.4%). |
| Cobalt Chloride (CoCl₂) Content | EDTA Complexometric Titration | Titrate cobalt ions with an EDTA standard solution in an ammonia buffer solution at pH ≈ 10, using Eriochrome Black T as the indicator to calculate CoCl₂ content. |
| Cobalt (Co) Content | Atomic Absorption Spectroscopy (AAS) or ICP-OES | Solve the sample in acid, then determine the cobalt element concentration using atomic absorption or inductively coupled plasma optical emission spectroscopy, and convert it to CoCl₂ content. |
| Chloride Ion (Cl⁻) Content | Argentometric Titration (Mohr Method or Potentiometric Titration) | Titrate Cl⁻ in the sample solution with AgNO₃ standard solution, using K₂CrO₄ as the indicator (Mohr method) or detecting the endpoint via electrode. |
| pH Value | pH Meter Measurement | Prepare a 1% aqueous solution of the sample and measure its pH using a calibrated pH meter, typically ranging from 4.0 to 6.0. |
| Water-insoluble Matter | Filtration and Weighing Method | Dissolve the sample in water, filter, wash, dry the insoluble residue, and weigh it to calculate the content, which should be ≤ 0.05%. |
| Heavy Metal Impurities | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Dissolve the sample in acid and determine the content of heavy metals such as lead, cadmium, arsenic, and copper, complying with pharmacopoeia or industrial standards limits (e.g., ≤ 10 ppm). |
| Sulfate (SO₄²⁻) Content | Turbidimetry (Barium Chloride Precipitation Method) | Add barium chloride solution to form BaSO₄ precipitate, compare turbidity with a standard solution, and control sulfate content to ≤ 0.01%. |
| Iron (Fe) Content | 1,10-Phenanthroline Spectrophotometry | Under reducing conditions, Fe²⁺ forms an orange-red complex with 1,10-phenanthroline, and the absorbance is measured at 510 nm for quantification. |
| Residue on Ignition (Ash Content) | High-temperature Incineration and Weighing Method | Incinerate the sample at 800°C in a muffle furnace until constant weight, calculate the ash content, which should be ≤ 0.1%. |
| Particle Size Distribution | Laser Particle Size Analyzer or Sieving Method | Determine the particle size distribution of the crystals to ensure compliance with process requirements (e.g., D50 range), avoiding clumping or uneven dissolution. |
