Manufacturing Quality Control of Zirconium sulphate
| Test Item | Common Test Methods | Method Overview |
|---|---|---|
| Main Component Content (ZrO₂ or Zr(SO₄)₂) | Volumetric Method (EDTA Complexometric Titration) | The sample is dissolved and titrated with a standard EDTA solution using xylenol orange as indicator in a buffer solution at pH 5–6 to determine zirconium ion content, from which the ZrO₂ content is calculated. Suitable for determination of high zirconium concentrations. |
| Sulfate Content | Gravimetric Precipitation Method or Ion Chromatography | Precipitation method: Barium chloride is added to precipitate sulfate as BaSO₄, which is then filtered, ignited, weighed, and used to calculate sulfate content. Ion chromatography: SO₄²⁻ concentration in solution is directly measured by ion chromatograph, offering high sensitivity. |
| pH Value | pH Meter Method | A certain amount of sample is dissolved in purified water, and the pH is measured using a calibrated pH meter to assess acidity. Typically, a 1% aqueous solution should have a pH between 1.0 and 3.0. |
| Insoluble Matter | Gravimetric Method | The sample is dissolved in water and filtered through a membrane filter or glass crucible. The residue is dried to constant weight and weighed to calculate the percentage of insoluble matter, used to evaluate purity and particulate impurities. |
| Heavy Metal Content | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, heavy metal elements such as lead, cadmium, chromium, and nickel are determined using atomic absorption spectroscopy or inductively coupled plasma mass spectrometry (ICP-MS), ensuring compliance with pharmaceutical or industrial standards. |
| Iron Content | Spectrophotometry (Sulfosalicylic Acid Method) | In an ammonia alkaline medium, iron forms a colored complex with sulfosalicylic acid. The absorbance is measured at a specific wavelength (e.g., 420 nm) to quantify iron impurities. |
| Chloride Content | Turbidimetry or Ion Chromatography | After adding silver nitrate, chloride ions form a turbid AgCl suspension; turbidity is measured using a turbidimeter. Alternatively, ion chromatography provides direct, sensitive, and accurate quantification. |
| Loss on Drying | Gravimetric Method (Oven Drying) | A known quantity of sample is dried at 105°C to constant weight. The weight loss is used to calculate moisture and volatile content. |
| Residue on Ignition | Gravimetric Method (High-Temperature Ignition) | The sample is ignited at high temperature (approximately 800°C) in a muffle furnace to remove volatile substances. The remaining residue is weighed to assess total inorganic impurities. |
| Microbial Limits | Microbiological Culture Method (Pharmacopoeia Method) | Total aerobic microbial count, mold and yeast count, and specified microorganisms (e.g., Escherichia coli) are tested according to the Chinese Pharmacopoeia or relevant standards. Applicable for pharmaceutical-grade products. |
