Manufacturing Quality Control of Strontium carbonate
| Detection Item | Common Detection Methods | Method Overview |
|---|---|---|
| Main Content (SrCO₃ Purity) | Complexometric Titration (EDTA Titration) | In a pH 10 buffer solution, titrate Sr²⁺ with a standard EDTA solution, using Eriochrome Black T or Calcein as the indicator, to calculate the strontium carbonate content. |
| Acid-Base Titration | React the sample with excess hydrochloric acid to release CO₂, then back-titrate the remaining hydrochloric acid with a standard NaOH solution to indirectly calculate the carbonate content. | |
| Moisutre Content | Drying Loss Method (Gravimetric Method) | Dry a specified amount of sample to constant weight at 105–110°C, and calculate moisture content based on mass loss. |
| Loss on Ignition | Igination Loss Method | Ignite the sample at high temperature (approximately 950–1000°C) to decompose carbonates, and calculate the total amount of CO₂ and volatile substances based on mass reduction. |
| Chlorides | Turbidimetric Method (Silver Nitrate Turbidimetry) | Dissolve the sample and add silver nitrate in a nitric acid medium to form silver chloride turbidity; quantify by comparing with standard turbidity series. |
| Sulfates | Turbidimetric Method or Gravimetric Method | Turbidimetric method: Add barium chloride under acidic conditions to form barium sulfate turbidity for measurement by turbidity; gravimetric method: Precipitate, filter, and weigh for higher accuracy. |
| Heavy Metals (e.g., Pb, Cu, etc.) | Atomic Absorption Spectroscopy (AAS) | After acid digestion of the sample, measure the absorbance of specific metal elements at their characteristic wavelengths using AAS for quantitative analysis of heavy metal impurities. |
| Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | High sensitivity method capable of simultaneously detecting multiple trace metal impurities, suitable for quality control of high-purity strontium carbonate. | |
| Iron Content | Spectrophotometry (o-Phenanthroline Method) | Iron ions form an orange-red complex with o-phenanthroline; measure absorbance at 510 nm for quantitative determination of iron impurities. |
| Fineness (Particle Size Distribution) | Laser Diffraction Particle Size Analysis | Utilize laser scattering principles to determine particle size distribution and evaluate physical properties of the product. |
| Sieving Method | Perform mechanical sieving using standard sieves to determine the proportion of particles in different size ranges. | |
| Whiteness | Whiteness Meter Method | Use a whiteness meter to measure the surface whiteness value of the sample under specific lighting conditions to assess appearance quality. |
| pH Value | pH Meter Method | Prepare a water suspension of the sample, stir, allow to settle, then insert a pH electrode to measure the pH value, reflecting the presence of acidic or alkaline impurities. |
