摘要
Ammonium can change the type of natural clinoptilolite from Jinyun ofZhejiang Province of China. The character of exchange and selectivity of ammonium type clinoptilolite to the alkali and alkaline - earth metal were investigated, the heatresistance and nitric acid - resistance of natural clinoptilolitewere discussed. All types of clinoptilolite were researched by means of X - ray,IR spectroscopy, DTA analyses. The ion exchange was experimented by columnoperation, indicating that the valid amount of exchange capacity of NH+4 typeclinoptilolite is more than 25mg/g.
