Ion Exchange Method for Preparation of Ammonium Paratungstate

Ammonium paratungstate, APT for short, is an important inorganic salt product with chemical formula (NH4)10(H2W12O42) ·4H2O. There are many ways to prepare APT, including ion exchange method, neutralization method, solvent extraction method, ultrasonic method, two step ion exchange method, evaporation crystallization method, and tungstic acid method, etc. Wherein, ion exchange process is attracted much attention.

Characteristics of Ion Exchange Method to Prepare Ammonium Paratungstate

Adsorb sodium tungstate solution through anion resin, then resolve with ammonium chloride - ammonium hydroxide mixed solution to obtain ammonium tungstate solution, and then evaporated and crystallized to obtain ammonium paratungstate product.

Preparation of Ammonium Paratungstate by Ion Exchange Method

The ion exchange process for preparing APT generally includes the following steps: crushing, alkaline cooking, pressure filtration, ion exchange, crystallization, and drying, etc.

The advantages of ion exchange process for preparing APT: short production process, low cost, simple equipment, and easy operation, etc.
