方沸石

Analcime is one of the zeolite minerals and have been interested both domestic and abroad in recent years.

方沸石是沸石族矿物的一种，是近些年国内外比较重视的新兴矿物资源。

In 20℃ and 40℃, the selectivity of Cd~(2+) to analcime is less than that of Na~+ to analcime; in 60~(2+) and 80℃,the selectivity of Cd~(2+) to analcime is more than that of Na~+ to analcime.

在20℃和40℃时，方沸石对Cd~(2+)的选择性小于对Na~+的选择性，在60℃和80℃时，方沸石对Cd~(2+)的选择性大于对Na~+的选择性。

The higher alkali concentration is favorable for emergence of montmorillonite,while the higher temperature is favorable for emergence of analcime.

其中碱浓度的增加有利于蒙脱石的生成，温度的升高则有利于方沸石的生成

The ion exchange capability and application of analcime and Cd~(2+) were investigated which offer directive theory for exploitation and utilize of analcime.

本论文主要研究了合成的方沸石与重金属Cd~(2+)的交换性能及其应用，对方沸石的开发和利用具有重要的理论指导意义。

In the same initial Cd~(2+) concentration, the amount of Cd~(2+) exchange in analcime increases with the rise of temperature. Under the same temperature the amount of Cd~(2+) exchange in analcime also increases as the initial Cd~(2+) concentration increases.

实验证明，当Cd~(2+)的初始浓度相同时，随着温度的升高，方沸石对Cd~(2+)的交换量增加；当温度相同时，随着交换液Cd~(2+)初始浓度的增加，方沸石对Cd~(2+)的交换量也随之增加。

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。

Palygorskite would transform into montmorillonite and analcime.

坡缕石经碱溶处理后可以转变成蒙脱石和方沸石。

Porous analcite balls were prepared from the analcite rocks after purifying and modification and then were used to remove fluorine.
