摘要
回收废催化剂中钨钼时须将钨钼尽量分离,根据钨酸根、钼酸根离子在不同酸度条件下,生成同多酸显示出不同溶解性的差别,应用于生产过程分离钨钼,工序简化,经济可靠,生产出符合市场需要的钨酸盐和钼酸盐产品。
Tungsten and molybdenum must be separated to the greatest extent from the waste catalysts. In different acidity conditions, wolframate radical and molybic radical generate into isopolyacid which show dissimilar dissolu- bility. According to this law, tungsten and molybdenum were separated in productive process. This technology has the advantages of simple procedure, cheap and reliable with the products meeting the market demand.
