When storing Ammonium Metatungstate Dispersions, the following points need to be noted to ensure its stability and safety:
- Storage environment
Temperature
Ammonium metatungstate should be stored in a cool and ventilated warehouse, and the temperature of the warehouse should not be more than 37℃, in order to avoid decomposition or performance degradation caused by high temperature. Meanwhile, exposure of the dispersion to too low temperature should also be avoided to prevent freezing.
Light
Direct sunlight should be avoided as it may trigger chemical reactions and affect the stability of the dispersion. Therefore, it is best to store the dispersions in containers protected from light, such as brown bottles or black bags.
Humidity
Ammonium metatungstate is a substance susceptible to moisture, so it is necessary to keep the storage environment dry. Desiccant or humidity regulator can be used to control the environment humidity to prevent the dispersion from absorbing moisture in the air and deteriorating.
- Container Selection
Sealing
In order to prevent the dispersant from moisture and volatilization, a container with good sealing should be selected for storage. Glass bottles or volumetric bottles are better choices, because they can prevent gas exchange, but also can withstand certain pressure changes.
Material
The material of the container should be compatible with the ammonium metatungstate dispersion to avoid chemical reaction. At the same time, the container should have certain corrosion resistance to prevent leakage due to corrosion by dispersing liquid.
Storage conditions
Avoid mixed storage
Ammonium metatungstate dispersing liquid should be avoided to be stored separately with oxidizing agent, edible chemicals and so on, and never mixed storage. This is because chemical reactions may occur between them, resulting in deterioration of the dispersion or the production of toxic and harmful substances.
Fire and explosion prevention
Since ammonium metatungstate has flammable and explosive properties, the storage place should be far away from fire and heat sources, and equipped with corresponding fire-fighting equipment and leakage emergency treatment equipment. Meanwhile, explosion-proof ventilation system and equipment should be used to reduce the risk of fire and explosion.
Static electricity protection
When storing and transferring dispersant, measures should be taken to prevent static electricity from building up, such as controlling the flow rate and using grounding devices. Static electricity may cause fires or explosions, posing hazards to people and property.
- Operating Precautions
Operator Training
Operators should be specially trained to understand the nature and storage requirements of ammonium metatungstate dispersing liquid, and to master the correct operation methods and emergency treatment measures.
Personal protection
When contacting the dispersing liquid, personal protective equipment such as protective clothing, gloves, protective glasses and respirator should be worn to prevent injury to the skin, eyes and respiratory system.
Ventilation
Operation and disposal should be carried out in places with local ventilation or comprehensive ventilation and air exchange facilities to reduce the accumulation of harmful gases and dusts and the harm to human body.
In summary, preservation of ammonium metatungstate dispersion needs to pay attention to many aspects such as storage environment, container selection, storage conditions and operation precautions. By adopting suitable measures and methods, the stability and safety of dispersions can be ensured, providing reliable guarantee for experiment and production.
