| 摘 要： | 利用氨氮吸附静态实验、电镜扫描、X衍射谱图分析以及化学成分分析方法探讨沸石结构对沸石吸附性能的影响机理。结果表明，在实验条件相同的情况下，不同沸石的吸附(NH4^ -N)容量差别十分显著，最高为0．83mmol／g计，最低仅为0．24mmol／g;沸石结构、孔隙分布以及化学成分是影响沸石吸附容量的主要内部因素，结构松散、孔径相对较大、孔径均匀的沸石吸附容量相对较高。

| Abstract: | Zeolite is known for its ability to remove ammonium from wastewater because it has a crystal structure with windows, cages, and supercages. The absorbent experiment indicate that the ion exchange capacity of zeolites varies in the range of 0.24 and 0.83 mmol/g. The results of the rochy identification indicate that the zeolite's absorbent ability against ammonium ions is mostly affected by its interior structure, for example, its molecular size, properties, crystal structure and so on. |
