摘要： Ammonium metatungstate is produced by contacting the anolyte side of a cation exchange membrane with an aqueous solution of ammonium tungstate and applying an electrical potential across the membrane such as to effect the transport of ammonium ions from said solution through the membrane to lowerthe pH of the solution to a level at which ammonium metatungstate is formed.

摘要翻译： 通过使阳离子交换膜的阳极电解液侧与钨酸铵的水溶液接触并在膜上施加电势以使铵离子从所述溶液中运输通过膜来降低pH值，从而产生偏钨酸铵 溶液达到形成偏钨酸铵的水平。
