Abstract
The invention discloses an ionic exchanging technology to prepare ammonium tungstate solution, which comprises the following steps: adopting acid solution to regenerate for large-hole faintly alkaline negative resin; adjusting each solution with tungsten at 4-5; proceeding resin adsorption disposal; washing to neutral through negative tungsten resin; blending ammonia and ammonium salt; proceeding adsorption through negative tungsten resin after linear-flow speed from rapid to slow; removing impurity; conversing to produce the product. The invention is simple to operate, which guarantees the quality of ammonium tungstate solution.
