Industrial Applications of Potassium oxalate
| Industry | Application | Process Description |
|---|---|---|
| Chemical Industry | Chelating Agent | Used to prepare metal chelates, such as stable complexes with iron, aluminum, and other metals |
| Metal Processing | Cleaning Agent | Applied to remove oxides and rust from metal surfaces, serving as an additive in acid pickling |
| Textile Industry | Dyeing Auxiliary | Used as a mordant in dyeing processes to enhance dye fixation |
| Pharmaceutical Industry | Intermediate in Drug Synthesis | Used in the synthesis of certain organic pharmaceuticals and intermediates |
| Laboratory Applications | Analytical Reagent | Used in quantitative analysis for standardizing oxidizing agent solutions, such as potassium permanganate |
| Food Industry | Food Additive (Limited Use) | Functions as an acidity regulator or stabilizer, subject to regulatory limits under food safety standards |
| Electronics Industry | Cleaning and Etching | Applied in surface treatment of electronic components to remove metal oxide layers |
Manufacturing Quality Control of Potassium oxalate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (K2C2O4 content) | Acid-base titration with KMnO4 | Oxalate is oxidized by standardized KMnO4 in acidic medium; endpoint detected by persistent pink color. |
| Loss on drying | Gravimetric method at 105 C | Sample is dried at 105 C until constant weight; mass loss reflects volatile impurities and moisture. |
| Water content | Karl Fischer titration | Quantitative reaction of water with iodine and sulfur dioxide in pyridine/methanol medium; coulometric or volumetric detection. |
| Heavy metals (as Pb) | Atomic absorption spectroscopy (AAS) | Sample digested and atomized; absorbance measured at characteristic wavelength for lead. |
| Sulfate (SO4) | Gravimetric precipitation with BaCl2 | Sulfate precipitated as BaSO4, filtered, dried, and weighed to determine sulfate content. |
| Chloride (Cl) | Potentiometric titration with AgNO3 | Chloride ions titrated with silver nitrate using silver indicator electrode; endpoint at inflection point. |
| Iron (Fe) | UV-Vis spectrophotometry (1,10-phenanthroline) | Fe2+ forms orange-red complex with 1,10-phenanthroline; absorbance measured at ~510 nm. |
| pH of aqueous solution | Potentiometric pH measurement | pH determined using calibrated glass electrode in 1% w/v aqueous solution. |
| Insoluble matter | Gravimetric filtration | Sample dissolved, filtered through pre-weighed sintered glass crucible, dried, and residue weighed. |
| Arsenic (As) | Hydride generation AAS (HG-AAS) | Arsenic reduced to arsine gas, swept into quartz cell, atomized, and quantified by AAS. |
| Residue on ignition | Gravimetric method at 600 C | Ignition at 600 C converts organic impurities to volatiles; residue mass reflects inorganic ash. |
| Bulk density | Volumetric displacement method | Mass of sample poured into calibrated cylinder; density calculated from mass and settled volume. |
