Manufacturing Quality Control of Rubidium sulfate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Rubidium Content | Flame Atomic Absorption Spectrometry (FAAS) | Measures absorbance of Rb+ ions at characteristic wavelength after atomization in air-acetylene flame. |
| Sulfate Content | Gravimetric Analysis | Precipitates sulfate as BaSO4 and determines mass after filtration and drying. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Uses silver nitrate titrant and silver indicator electrode to detect endpoint via potential change. |
| Heavy Metals (Pb, Cd, Ni, etc.) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Atomizes and excites sample in plasma; quantifies metals by element-specific emission intensities. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in methanol-based reagent. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determines hydrogen ion activity using calibrated glass electrode and reference electrode in 1% w/v solution. |
| Insoluble Matter | Gravimetric Filtration | Filters aqueous solution through pre-weighed sintered glass crucible and weighs residue after drying. |
| Iron Impurity | UV-Vis Spectrophotometry (with 1,10-phenanthroline) | Forms orange-red Fe(II)-phenanthroline complex; measures absorbance at ~510 nm. |
| Ammonium Impurity | Distillation followed by Nesslerization | Distills NH4+ under alkaline conditions; reacts distillate with Nessler's reagent to form yellow-brown complex. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying | Measures mass loss after heating at 105 C for 2 hours to remove volatile components. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles against white background under controlled lighting. |
| Bulk Density | Volumetric Method (ASTM D1895) | Determines mass per unit volume using standardized funnel and graduated cylinder under specified tapping conditions. |
