The advantages and disadvantages of ammonium metatungstate solvent extraction can be summarized as follows:
Advantages of ammonium metatungstate solvent extraction
High sensitivity and selectivity
Solvent extraction can effectively and selectively extract specific components in ammonium tungstate, such as ammonium ions, from the mixture, thereby realizing the preparation of ammonium metatungstate.
Simple equipment and fast operation
Compared with other complex preparation processes, the equipment used in solvent extraction is relatively simple and the operation is faster.
Good separation effect
Through solvent extraction, the separation of different components in ammonium tungstate can be better achieved, and ammonium metatungstate products with higher purity can be obtained.
Short process flow and small footprint
This is conducive to reducing production costs and land resource occupation.
Waste liquid can be returned to the process
It is conducive to environmental protection and resource reuse.
The process is continuous and easy to automate: it can improve production efficiency and product quality.
Disadvantages of ammonium metatungstate solvent extraction
Large workload
Especially in batch sample analysis, the workload of solvent extraction is relatively large.
The extraction solvent is volatile, flammable and toxic.
During the operation, special attention should be paid to safety to avoid the volatilization and leakage of the solvent to prevent harm to the environment and operators.
The extraction process cannot effectively separate impurities such as phosphorus, arsenic, silicon, and molybdenum.
This may lead to a high impurity content in the product, requiring subsequent additional purification steps.
The extraction process is prone to produce solids and cause emulsification.
This may affect the stability and continuity of the entire process, increasing the difficulty and cost of operation.
High temperature control requirements
Since ammonium metatungstate is highly soluble in water, easy to deliquesce in the air, and has poor stability, the temperature needs to be strictly controlled during the dehydration process, otherwise it may cause the crystals to melt and affect the product quality.
In summary, the ammonium metatungstate solvent extraction method has its unique advantages and disadvantages, and it needs to be selected and adjusted according to the specific situation in practical applications.
