When the pH value of the solution contained in Cd~(2+) is near 5, the amount of Cd~(2+) exchange in analcime reaches to a summit; when the temperature increases, the amount of Cd~(2+) exchange in unit mass analcime also increases; when initial Cd~(2+) concentration decreases, the remove rate of Cd~(2+) increases while the amount of Cd~(2+) exchange in unit mass analcime also decreases; when other cations coexist in solution, there must be some influences to the Cd~(2+) exchange in analcime.

实验表明：当交换液的pH值为5左右时，方沸石对Cd~(2+)交换量较大：反应温度升高时，单位质量方沸石对Cd~(2+)交换量增大；随着溶液中Cd~(2+)初始浓度减小，方沸石对Cd~(2+)的去除率升高，但单位质量方沸石对Cd~(2+)的交换量逐渐减小；当溶液中有其他阳离子共存时，对方沸石与Cd~(2+)的交换也有一定的影响。
