Japanese Patent JP5651164

B2

A method for producing an ammonium tungstate aqueous solution, comprising the steps of: producing a polyacid solution containing poly tungstate ions and Mo-containing polyacid ions, adsorbing said poly tungstate ions to a first anion exchange resin of an anion exchange resin and adsorbing said Mo-containing polyacid ions to a second anion exchange resin of said anion exchange resin by supplying said polyacid solution to said anion exchange resin constituted of said first anion exchange resin and said second anion exchange resin connected to each other, such that said first anion exchange resin is first supplied with said polyacid solution, disconnecting said first anion exchange resin and said second anion exchange resin from each other, and bringing an aqueous solution containing ammonium ions, into contact with said first anion exchange resin after the step of disconnecting.
