The linear relationship between calcium ion exchange capacity and framework aluminum content of zeolite NaX was found, and the effects of exchange temperature, concentration of zeolite and other cations on calcium ion exchange behavior were also investigated. The sequence of the calcium ion exchange selectivity of zeolite MAP, NaA and NaP was determined. The framework structure of zeolite NaA, NaX and NaP significantly influence the cation exchange behavior of these three zeolites.展开更多
