Taking acid-treated stellerite as main material, zeolite X powder was prepared by hydrothermal method.

以酸处理红辉沸石为主要原料,采用水热法制备了X型沸石粉。

The results indicate that the modification by heating and acids could not significantly increase the adsorption capacity of the modified stellerite for ammonia nitrogen.

表明，加热性与无机酸性不能显著提高沸石对吸附量。
