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

以理红辉为主要原料,采用水热法制备了X型粉体。

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，加热改性与无机改性不能显著对氨氮的吸附量。
