Oxalic Acid Buy Online

1. Invisible assistant in art restoration
Bronze reduction technique: In cultural relic restoration, oxalic acid solution is used to accurately remove green basic copper carbonate (patina) on the surface of bronze artifacts, restore the original color of the metal through reduction reaction, and avoid damage to cultural relics caused by mechanical polishing.

Oil painting restoration: Diluted oxalic acid can gently dissolve the oxide layer of aged oil paintings, helping restorers to restore the original color of the paintings without damaging the pigment layer.

2. Stress resistance code in biotechnology
Plant aluminum poisoning antidote: In acidic soil, oxalic acid combines with aluminum ions to form a stable complex, which is used in the gene expression regulation of some genetically modified crops (such as alfalfa), helping plants resist aluminum poisoning and improving the survival rate of crops in barren land.

Fungal symbiotic medium: Some mycorrhizal fungi decompose minerals in the soil by secreting oxalic acid, promoting the absorption of phosphorus by plants. This mechanism is used to develop new biofertilizers.

3. The driving force behind new energy materials
Purification of lithium battery materials: In the preparation of lithium battery cathode materials (such as lithium iron phosphate), oxalic acid as a precipitant can accurately control the crystal particle size and improve the battery charging and discharging efficiency.

Fuel cell catalyst: Platinum-based nanocatalysts synthesized with the assistance of oxalic acid show higher oxygen reduction activity than traditional methods, promoting the advancement of hydrogen fuel cell technology.

4. Molecular catcher in environmental engineering
Nuclear waste treatment: Oxalic acid forms a soluble complex with uranyl ions (UO₂²⁺), which is used for wet separation and purification of nuclear waste, which is more selective than traditional methods.

Rare earth element recovery: From discarded electronic products, oxalic acid preferentially precipitates specific rare earth elements (such as lanthanide metals) to achieve efficient and environmentally friendly resource recovery.

5. Special solvents for cutting-edge manufacturing
Microelectronics cleaning fluid: In semiconductor manufacturing, ultra-pure oxalic acid solution is used to remove metal ion contaminants from the surface of silicon wafers, and its low corrosiveness is better than conventional strong acids.

Graphene preparation: As an intercalation agent to assist in the exfoliation of graphite, few-layer graphene is prepared through a redox process, which is more environmentally friendly than the traditional Hummers method.
