Manufacturing Quality Control of AMMONIUM PENTABORATE TETRAHYDRATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (NH4)3B5O9.4H2O | Acid-Base Titration | Direct titration with standardized HCl after dissolution and controlled hydrolysis to liberate boric acid, followed by mannitol complexation and NaOH back-titration. |
| Boron Content | ICP-OES | Quantification of total boron after acid digestion and dilution, based on characteristic atomic emission lines of boron. |
| Ammonium Content | Kjeldahl Nitrogen Analysis | Digestion with sulfuric acid and catalyst, distillation of liberated ammonia into boric acid solution, followed by titration. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification after microwave-assisted acid digestion; detection at trace levels using mass spectrometry. |
| Chloride Impurity | Potentiometric Titration | Titration with standardized silver nitrate using silver indicator electrode; endpoint detected by potential change. |
| Sulfate Impurity | Gravimetric Analysis | Precipitation as barium sulfate under controlled conditions, followed by filtration, drying, and weighing. |
| Loss on Drying (LOD) | Thermogravimetric Analysis (TGA) | Mass loss measured upon heating from 25 to 105 C under nitrogen, representing volatile content including water of hydration. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measurement of hydrogen ion activity in a 1% w/v aqueous solution using calibrated pH electrode. |
| Iron Impurity | AAS | Atomic absorption spectroscopy after acid digestion and matrix matching; quantification via iron-specific hollow cathode lamp. |
| Residue on Ignition | Gravimetric Analysis | Mass of non-volatile residue remaining after ignition at 800 C for 1 hour in platinum crucible. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered light intensity pattern from dispersed sample to determine volume-based particle size distribution. |
| Microbial Contamination | Membrane Filtration | Filtration of aqueous solution through sterile membrane, followed by incubation on appropriate agar media and colony enumeration. |
