| Water Treatment | Precipitant, flocculant | Complexes with heavy metal ions to form precipitates, enabling heavy metal removal in wastewater treatment |
Manufacturing Quality Control of POTASSIUM ALGINATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Potassium Alginate Content) | Acid-Base Titration | Neutralization of carboxylic acid groups with standardized NaOH after acid hydrolysis and back-titration. |
| Moisture Content | Karl Fischer Titration | Quantitative reaction of water with iodine and sulfur dioxide in a methanol-based reagent, measured coulometrically or volumetrically. |
| Ash Content | Gravimetric Analysis | Incineration at 500-600 C to oxidize organic matter, followed by weighing of residual inorganic ash. |
| pH (1% aqueous solution) | pH Potentiometry | Measurement of hydrogen ion activity using calibrated glass electrode in a standardized aqueous suspension. |
| Viscosity (1% solution, 25 C) | Capillary Viscometry | Determination of kinematic viscosity based on flow time through a calibrated capillary tube under gravity. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal ions via absorption of specific wavelength light by ground-state atoms in a flame or graphite furnace. |
| Arsenic | Hydride Generation-AAS (HG-AAS) | Reduction of arsenic to arsine gas, swept into quartz cell for atomic absorption measurement. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample with sulfuric acid pretreatment to convert metals to stable sulfates, then weighing residue. |
| Residual Solvents (e.g., ethanol, isopropanol) | Gas Chromatography (GC-FID) | Separation and quantification based on retention time and flame ionization detection response. |
| Microbial Limits (Total Aerobic Count) | Plate Count Agar Culture | Enumeration of viable aerobic microorganisms after incubation on nutrient agar under specified conditions. |
| Particle Size Distribution | Laser Diffraction | Analysis of angular scattering pattern of laser beam passed through dispersed particles to calculate size distribution. |
| Chloride Content | Potentiometric Titration with AgNO3 | Titration with silver nitrate using silver indicator electrode to detect endpoint of AgCl precipitation. |
