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

以处理红辉沸要原料,采用水热法制备了X型沸粉体。

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

结果表明，加热与无机不能显著提高沸对氨氮的吸附量。
