Manufacturing Quality Control of AMMONIUM PENTABORATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (NH4)3B5O9.H2O | Acid-Base Titration | Quantifies total borate content via back-titration after alkaline hydrolysis and acid addition. |
| Loss on Drying | Gravimetric Analysis | Measures weight loss after drying at 105 C to determine moisture and volatile content. |
| pH of Aqueous Solution | Potentiometric Titration | Determines pH of 1% w/v aqueous suspension using calibrated pH electrode. |
| Chloride (Cl-) | Potentiometric Titration with AgNO3 | Measures chloride by silver nitrate titration using silver indicator electrode. |
| Sulfate (SO42-) | Gravimetric Analysis | Precipitates sulfate as BaSO4 and quantifies by weighing the dried precipitate. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies lead and other heavy metals after acid digestion and flame or graphite furnace AAS. |
| Iron (Fe) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Measures iron concentration following sample dissolution and plasma excitation. |
| Insoluble Matter | Filtration and Gravimetry | Determines residue retained on 5-micron filter after aqueous suspension and drying. |
| Ammonium (NH4+) | Distillation followed by Titration | Releases NH4+ by alkaline distillation, then titrates liberated ammonia with standardized acid. |
| Boron (Total B) | Curcumin Colorimetric Method (UV-Vis) | Forms pink boron-curcumin complex in acidic medium; absorbance measured at ~540 nm. |
| Sodium (Na) and Potassium (K) | ICP-OES | Simultaneously quantifies alkali metals after acid digestion and plasma emission detection. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of dry powder using Mie scattering theory and laser diffraction optics. |
