In the production process of Ammonium Metatungstate, the addition of ammonia is a key step, and the following conditions and matters need to be paid attention to in order to ensure the smooth progress of the production process and the quality of the final product:
Safety measures
Wear acid and alkali neutral protective gloves, goggles and protective clothing to avoid skin or eye injury caused by direct contact with ammonia.
Keep the operation area well ventilated and ensure that there is adequate fire extinguishing equipment to prevent fire in case of ammonia leakage or spillage.
In case of accidental contact, immediately flush with plenty of water and seek medical attention.
Preparation of ammonia containers and equipment
Check labels and seals of ammonia containers to ensure no damage or leaks.
Prepare clean containers and agitators, ensuring that their surfaces and interiors are free of contamination.
Procedure
Quantitatively prepare the required ammonia and other reactants.
Pour in the ammonia slowly, taking care to control the rate of pouring to avoid spilling or splashing.
Gradually pour the ammonia into the container while stirring continuously until the desired addition is reached.
Close the container to ensure a tight seal.
Parameter control
Control the temperature to ensure that the ammonia addition and reaction is carried out at the appropriate temperature conditions.
Monitor the pH to ensure that it is within the appropriate range for the reaction, e.g. pH 2 to 4.
Control the stirring speed to ensure that the reactants are well mixed and reacted.
Subsequent processing
After the ammonia addition is completed, pay attention to check whether there is any ammonia overflow from the outside of the container and clean it in time.
Store the container with the added ammonia in the prescribed manner or continue with the subsequent operation.
Precautions
Avoid direct contact with skin and eyes to prevent injury caused by ammonia.
Keep the operating area well ventilated continuously during operation to avoid accumulation of harmful gases.
Follow the operating instructions, first aid measures and emergency dispositions in the Ammonia Safety Data Sheet.
By following the above conditions and precautions, the safety and accuracy of the ammonia addition step in the ammonium metatungstate production process can be ensured, thus safeguarding the quality of the final product.
