摘要
多钨酸钠是一种无毒、无气味、易溶解、易配制、稳定性好、回收率高、使用方便安全的新型无机重液 ,其密度变化范围为 1.0g/cm3～ 3 .1g/cm3,分离缙云沸石和粘土矿物取得了良好的效果。详述了多钨酸钠溶液的配制和回收 ,分离缙云沸石和粘土的实验流程及其应用前景。
Sodium polytungstate is a new inorganic heavy liquid with no toxic compounds and no odors. Solutions with densities ranging from 1.0 g/cm 3 to 3.1 g/cm 3 can be prepared. It is easily diluted, has excellent stability, a high recycling rate, and is convenient and safe. Sodium polytungstate has been used to separate zeolites and clay minerals with success. This paper describes in detail the preparation and recycling of sodium polytungstate, the method of separation of the Jinyun zeolites and associated clay minerals, and an outlook on the future application of sodium polytungstate.
