Industrial Applications of COBALT GLUCONATE
| Industry | Application | Process |
|---|---|---|
| Petrochemicals | Catalyst | Used in heavy oil hydrodesulfurization, hydrodenitrogenation, and hydrocracking processes as an active component or promoter of hydrogenation catalysts. |
| Chemical Industry | Catalyst / Promoter | Serves as an oxidation catalyst in organic synthesis processes, such as the oxidation of p-xylene to terephthalic acid. |
| Coatings & Paints | Drying Agent | Applied in oxidative-drying coatings (e.g., alkyd resin paints) to accelerate surface oxidation, polymerization, and film curing. |
| Agriculture | Micronutrient Additive | Used in the production of micronutrient fertilizers or animal feed additives to supply cobalt required by plants or animals. |
| Food & Pharmaceuticals | Nutritional Fortificant / Raw Material | Serves as a source of cobalt for nutritional fortification in food products or as a raw material for cobalt supplementation in pharmaceutical formulations. |
Manufacturing Quality Control of COBALT GLUCONATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Cobalt Content) | ICP-OES or AAS | Quantifies cobalt concentration by measuring atomic emission (ICP-OES) or absorption (AAS) of cobalt ions in acid-digested sample solution. |
| Assay (Gluconic Acid Content) | Acid-Base Titration | Determines gluconic acid content via back-titration with standardized NaOH after esterification and hydrolysis. |
| Loss on Drying | Gravimetric (Thermogravimetric) | Measures mass loss after drying at 105 C to determine volatile content including water and residual solvents. |
| Water Content | Karl Fischer Titration | Quantifies water based on stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Detects trace heavy metals by mass spectrometric analysis of element-specific isotopes after microwave digestion. |
| Chloride Impurity | Potentiometric Titration | Measures chloride ion concentration using silver nitrate titrant and silver indicator electrode. |
| Sulfate Impurity | Gravimetric (Barium Sulfate Precipitation) | Determines sulfate as insoluble BaSO4 precipitate formed after addition of barium chloride in acidic medium. |
| pH of Aqueous Solution | Potentiometric (pH Meter) | Measures hydrogen ion activity in a 1% w/v aqueous solution using calibrated glass electrode system. |
| Residue on Ignition | Gravimetric | Quantifies non-volatile inorganic impurities by weighing residue remaining after high-temperature (700-800 C) ashing. |
| Microbial Limits | Membrane Filtration | Determines total aerobic microbial count and absence of specified pathogens (e.g., E. coli) using selective culture media. |
| Particle Size Distribution | Laser Diffraction | Analyzes particle size distribution by measuring angular variation in laser light scattering pattern of dispersed sample. |
| Appearance and Color | Visual Inspection | Assesses physical state (powder/crystals), color (white to off-white), and absence of foreign particles under controlled lighting. |
