The advantages and disadvantages of the preparation of ammonium metatungstate hydrate by ion exchange method are as follows:
Advantages of the process of preparing ammonium metatungstate hydrate by ion exchange method
Simple process
Compared with other methods, such as neutralization method and tungstic acid method, the process of ion exchange method is relatively simple, easy to operate and control.
Convenient control
In the ion exchange method, the process of the reaction and the quality of the product can be easily controlled by adjusting the parameters such as pH value and temperature.
Effectively improve the conversion rate
Ion exchange method can effectively improve the conversion rate from ammonium tungstate to ammonium metatungstate, so as to increase the product yield and reduce the cost.
Small investment in equipment
Compared with other complex production processes, ion exchange method requires less investment in equipment, which is suitable for small and medium-sized enterprises.
No introduction of new pollutants
Ion exchange does not introduce new pollutants into the production process, which is favorable to environmental protection.
Development potential
Since the ion exchange method has the above advantages, it has a large development potential in the field of ammonium metatungstate production.
Disadvantages of the process of preparing ammonium metatungstate hydrate by ion exchange method
A small amount of colloidal tungstic acid may be generated
A small amount of colloidal tungstic acid may be generated by the ion exchange method during the deammoniumization process, which may clog the resin layer and resin micropores, affecting the service life of the resin and the quality of the product.
Increased operation steps
Since the ion exchange method requires the use of resin, it is necessary to remove the tungsten liquid entrapped in the resin and regenerate the resin with acid during the production process, which increases the complexity of the operation steps.
Low metal recovery rate
The metal recovery rate of the ion exchange method may be low compared to other methods, which may affect product yield and economic efficiency.
Need for strong acid to regenerate the resin
The resin in the ion exchange method needs to be regenerated with strong acid, which increases the production cost and environmental pressure.
The preparation of ammonium metatungstate hydrate by ion exchange method has the advantages of simple process, convenient control and small investment in equipment, but it also has the disadvantages of possible generation of colloidal tungstic acid, increased operation steps and low metal recovery rate. In practical application, the most suitable production method needs to be selected based on comprehensive consideration of specific needs and conditions.
